Hi everyone,

I hope all are doing well. As I write this, I see the first signs of Fall. The air is a little less humid and the temperatures just a tad less oppressive. Most notable is the view out of my window as bright yellow spots go flapping and gliding by as the butterflies have started migrating, taking an exact South-southeast course to who knows where.

Oh, and are you ready for some football?

I hope you have a good month, and I hope to see you at our next meeting, which will be on September 12.

Roll Tide & War Eagle.

How Far Is Up?

If one “reads the traffic”, as they say, on various online radio forums, one question which persistently appears is the question of radio range. “I want to be able to keep in touch with Granny who is 75 miles from me when (insert ones favorite disaster scenario) hits. My Baofeng UV-5R that I got off of Amazon should do this shouldn’t it? The ad said so anyway.”

Then when someone answers that in all probability the answer is “no” and that both he and Granny would need ham licenses anyway, the usual collection of Kooks, Knuckleheads and Chuckleheads appear, assuring him that they talk to folk in Honolulu on 2 meters using simplex every day and “you don’t need no stinkin’ license in an emergency anyway. These folk sayin’ that you do are just gatekeepin’ Sad Hams. And, after all, why should man license what God created anyway? Don’t be spineless sheeple. Just transmit.”.

This isn’t exaggeration, there are folk out there with that mindset – far too many.

Radios can be complicated beasts. IF one is getting a radio for emergency use, one would think one would want to learn everything they could about the device they will be depending on for life and death situations. One would want to know how it works, where it works, where it doesn’t work and why and how to overcome the problems that may arise, along with which repeaters really working and are actually populated, not “RF Ghost Gowns” and when folk are most likely to be listening if you needed to call for help.

You learn all of this by first learning the material you need for passing the FCC exam, passing the exam and then learning through experience as you use the radio. Using it regularly and learning it’s quirks and perks. Using it so frequently that it becomes just a natural part of life. Switch to RF? No big deal, for you do so all the time. Also, I believe in having and using multiple options. I have ham, CB, GMRS/FRS and MURS capability. Not, just because I’m addicted to radios, which I am, but, because I like having the flexibility and redundancy.

You would also want to know how not to sound like a nut or someone on a bootleg or stolen radio. After all, if you sound like nut, folk will generally avoid you, since encouraging nuts and bootleggers is usually not a desirable action.

Plus, there is a huge credibility gap with unlicensed transmissions. Do they really have an emergency or are they just playing games?

I’ve heard bogus distress calls before. One was so realistic and well done that the Birmingham Fire & Rescue was summoned to a house with someone hemorrhaging, only to find it was a vacant field and another dramatic episode which resulted in the Birmingham Police being sent on a wild goose chase.

A callsign lends to credibility.

Also, consider this. If you are truly investing in equipment that you may be depending on for possible life and death use, then maybe you don’t want to rely on the cheapest piece of gear you can find. Save a little money and invest in quality. Think this through.

After all, and with apologies to those who own and love Baofeng and similar radios, which I also have, would you really want to go skydiving with the cheapest parachute from Bubba’s Thrift Store? If you or your loved one’s lives may someday depend on a piece of equipment – any equipment – one should choose wisely, opt for dependability and not just go the cheapest route available.

But, back to the question of radio range and why it is actually a difficult question to give an honest answer to, let’s journey for a while to the bustling metropolis of Mayberry, which is nestled in the shadow of the Appalachians.

To the west of Mayberry is Campbell Mountain, which has three repeaters – 146.720 MHz, 146.860 MHz and 147.100 MHz.

146.720 has been damaged by lightning. It’s transmitter is at full power and can be heard for 50 miles, but the zapped receiver is very weak. One trying to reach the repeat might wonder why, with such a strong signal they can’t hit it. It’s because the repeater is basically deaf. Or as they say, it is an “Alligator Station” – big mouth, tiny ears.

146.860 has the exact opposite problem. It has a great receiver, but the transmitter’s final amplifier is fried, and it is putting out 1/10th of a watt. One trying to get into the repeater can’t hear it, though the repeater is hearing and faithfully retransmitting a wisp of a signal. It has become an “Elephant Station” – big ears, tiny mouth.

147.100 has been off the air for years. The owner has every intention of reviving it, but currently can’t afford the replacement parts. Repeater databases still show it as on the air, but for actual use, it doesn’t exist. And since these databases are voluntary efforts, it may not have been updated for weeks, months or even years and is still shown as active. It is a “Paper Repeater”. Listed, but not only an illusion.

The best repeater is on Mount Pilot. 147.340, which has a 70 mile footprint, except to the northeast, as the antenna is side mounted on the southwestern side tower, and there is a RF shadow to the northeast. Anyone in that shadow may hear the repeater but, they won’t be able to hit it.

This is why Emmett on Bass Mountain 50 miles to the northeast can’t hear the repeater, but can contact his fishing buddy Floyd, who has a cabin on Mount Pilot, regularly on simplex, having no obstructions, and it being from mountain peak to mountain peak,

In the valley to the west of Mayberry, is the Pyle National Forest, named after a military hero. Camping there are Barney and Thelma Lou. The area is heavily forested, and Barney, who goes hiking gets deep into woods and loses contact with Thelma Lou on simplex after only 1000 feet. Barney also loses cellphone and GPS coverage as the forest canopy is blocking all signals.

Thelma Lou, who is camped by Darling Creek can’t hear Barney, but can see Mount Pilot and easily reach the repeater which is 15 miles away.

Meanwhile in town, Howard and Sam were talking to each other on simplex, but lost each other after going beyond one half mile separation, due to buildings blocking the signal, so they switched to the Mount Pilot repeater.

Thelma Lou, incidentally, could hear Sam faintly on simplex from 5 miles away as his signal was being reflected off of the sheer sides of Taylor Cliff on the southern side of Mount Pilot.

She switches to the Mount Pilot repeater and informs Howard and Sam that Barney has “done it again” and they call 911 to have Engine 3 and Sheriff Opie Taylor come out and find him yet again, as he is lost somewhere in the woods, something she has been trying to nip in the bud for years.

So…what radio range can an HT have around Mayberry?

Depending on who you talk to 1000 feet, half a mile, 50 miles or anywhere in the 70 mile repeater footprint (except in that northeastern shadow).

It’s exactly like cellphones, where you can have 5 bars of signal in the kitchen and none in the den. Can’t hit a repeater? Move over 5 feet and try it again.

This is why answering questions about range is as easy as asking “how far is up?” There are just too many variables. It is literally “in the eyes of the beholders” or in this case, the radio users.

This is why one needs to learn these variables long BEFORE an emergency, and not during, when lives are at stake and times is not on your side.

Learn today so you don’t regret later,

Mark’s Almanac

September is the ninth month of the year and the seventh month of the Roman calendar, which is where the month gets its name.

Temperatures are still hot at the beginning of the month, but, by months end, fall will definitely be felt.

Noticeable in September will be the thickening of the cat’s fur, as she begins growing her winter coat & the drift of Yellow Giant Sulphur Butterflies as they migrate towards Florida.

Weather starts shifting from the summer to autumn pattern and then back again. Storm activity resembles the August pattern, but the Bermuda High starts shifting southward and begins weakening, which weakens the blocking effect that has hampered fronts attempting to invade from the northwest.

September is the peak of the hurricane season, the actual peak being on September 10. This peak coincides with the time of “syzygy”, when the effects of the solar and lunar gravity and autumnal equinox combine to provide the highest astronomical tides of the year. Add a hurricane’s storm surge on top of this and you can have incredibly destructive flooding.

From 1851 – 2022 there have been 637 Tropical Storms, 3 Subtropical Storm and 423 hurricanes, 112 of which made landfall in the United States.

Some notable September hurricanes are:

The Galveston Hurricane of 1900, which was a Category 4 Storm whose storm surge overwhelmed Galveston Island, killing 8000 people, and is still the deadliest weather disaster in US history.

The Labor Day Hurricane of 1936, the most intense storm to strike the US, was a Category 5 storm which moved through the Florida Keys and along West Florida, overturning trains and literally sandblasting people to death.

Ivan, the category 3 storm which struck Alabama & Florida in 2004, caused tremendous damage to Gulf Shores and extensive damage to the state’s electrical grid. At the height of the outages, Alabama Power reported 489,000 subscribers having lost electrical power—roughly half of its subscriber base.

Rita, a category 3 storm which struck the Texas – Louisiana border in 2005, and, despite the distance, dropped 22 tornadoes over Western Alabama.

Ian, a category 4 storms which struck Florida in 2022, following the exact path of Hurricane Charley in August 2004.

 

 

 

Days continue to grow shorter as the Sun’s angle above the noonday horizon steadily decreases from 64.9 degrees at the beginning of the month to 53.6 degrees at the month’s end. Daylight decreases from 12 hours 52 minutes on August 1 to 11 hours 53 minutes on August 31.

 

Sunrise and sunset times for Birmingham are:

September 1 Sunrise 6:21 AM Sunset 7:13 PM
September 15 Sunrise 6:30 AM Sunset 6:55 PM
September 31 Sunrise 6:41 AM Sunset 6:33 PM

Looking skyward, the Sun, magnitude -26.7 is in Leo, The Lion.

Mercury, magnitude +0.3 in Leo, The Lion, is lost in the glow of the sun and will pass between the Sun and the Earth or be in “Inferior Conjunction” of September 6.

He will remain too close to the Sun for observation until September 19, when he will emerge into the predawn sky rising at 5:09 AM, 1 hour and 21 minutes before the Sun, reaching an altitude of just 10° above the eastern horizon before fading from view as dawn breaks around 6 AM.

He will reach peak altitude of 17° above the horizon at sunrise on 24 Sep 2023 and then will start sinking back towards the sunrise

By month’s end he will rise at 05:29 AM, 1 hour and 9 minutes before the Sun and reach an altitude of just 10° above the eastern horizon before fading from view as the dawn breaks, a little after 6 AM.

Venus, magnitude -4.1 in Cancer, The Crab, is an early morning object, rising, at the first of the month, at 4:24 AM, nearly two hours before the Sun, and reaching an altitude of 19° above the eastern horizon before fading from view as dawn breaks at around 6 AM.

She rises earlier and earlier as the month progresses, rising at 03:13 AM, nearly 3 hours 30 minutes before the Sun and reaching an altitude of 38° above the eastern horizon before fading from view as dawn breaks.

Earth, magnitude -4.0 as viewed from the Sun, and her Moon is in the constellation Aquarius, The Waterbearer.

Mars, magnitude +1.8, with his Moons Phobos and Deimos in Virgo, The Virgin, is lost in the glow of the Sun.

Dwarf Planet Ceres, magnitude 8.9, is in Virgo, The Virgin, is lost in the glow of the Sun.

Jupiter, magnitude –2.5, and his 95 moons and (invisible from Earth) ring, in Aries, The Ram,
dominates the early morning skies becoming visible at the first of the month around 11PM at an altitude of 7° above the eastern horizon.

He will reach his highest point around 5 AM, 71° above the southern horizon and sink to only 66° above the south-western horizon when he is lost in the dawn twilight around 6 AM.

By months end he becomes visible by 9 PM at an altitude of 7° above the eastern horizon and reaching his highest point in the sky at 3 AM, 71° above the southern horizon. He will be lost in the dawn twilight around just before 6:30, 39° above the western horizon.

Saturn, magnitude +0.5, and his 146 moons and extensive debris ring system, is in Aquarius, The Water Bearer, is an early morning object, rising at the first of the month becoming visible around 8 PM 10° above the eastern horizon.

He will reach its highest point in the sky at around 12:20 AM, 44° above the southern horizon. It will become inaccessible at around 5 AM when he sinks below 10° above the south-western horizon.

By months end he will rise at 8 PM, 23° above the south-eastern horizon, as dusk fades to darkness.

He reaches its highest point in the sky around 10:20 PM, 43° above the southern horizon. He
Will then sink towards the horizon, disappearing from view around 3 AM.

Uranus, magnitude +5.8, and his 27 moons and ring, in Aries, The Ram, is a morning object becoming visible around 10:30 PM and reaching his highest altitude of 74° above the southern horizon before fading from view as dawn breaks a little after 5 AM.

At mid-month he becomes visible around 11:30 PM and by months end he becomes visible around
10:30 PM reaching an altitude of 21° above your eastern horizon and then reaching highest point in the sky around 3:30 AM, 74° above the southern horizon. He will be lost to dawn twilight around 6:AM, 56° above the western horizon.

If the timing of when he becomes visible seems strange, 10:30,11:30 and then 10:20, it is because he has entered a “retrograde motion”, halting his usual eastward movement through the constellations, and turning to move westwards instead.

This reversal of direction is a phenomenon that all the solar system’s outer planets periodically undergo, a few months before they reach “Opposition”, when it lies opposite to the Sun in the sky.

The retrograde motion is caused by the Earth’s own motion around the Sun. As the Earth circles the Sun, our viewing perspective changes, and this causes the apparent positions of objects to move from side-to-side in the sky with a one-year period. This nodding motion is super-imposed on the planet’s long-term eastward motion through the constellations. He will complete this retrograde cycle in January.

Neptune, magnitude 7.7, and his 14 moons and ring, is in Pisces, The Fish, is visible using a telescope in the morning sky, becoming accessible around 10 PM, when it reaches an altitude of 21° above the eastern horizon. He will then reach its highest point in the sky at 2 AM, 53° above the southern horizon. It will be lost to dawn twilight around 05:17, 30° above your south-western horizon.

He will reach Opposition on September 19.

By months end he will become observable around just before 8 PM, when he rises to an altitude of 21° above the eastern horizon. He will reach its highest point in the sky at midnight, 53° above the southern horizon. It will become inaccessible at around 4 AM when he sinks below 21° above the western horizon.

Dwarf Planet Pluto, with his five moons shines at a dim +14.4 in Sagittarius, The Archer.

Dwarf Planet 136108 Haumea, her ring and moons Hiʻiaka and Namaka, shines at a faint magnitude of +17.4 in Bootes the Herdsman

Dwarf Planet 136472 Makemake with his moon S/2015 (136472) 1, nicknamed MK1 by the discovery team, shines faintly at magnitude +17.2 in Coma Berenices.

Dwarf Planet 136199 Eris and her moon Dysnomia, originally referred to as Xena and Gabrielle, is barely visible in the most powerful telescopes at magnitude +18.7 in Cetus the Sea Monster.

At least five additional bodies with the preliminary criteria for identifying dwarf planets, and though not “officially” declared as such, are generally called dwarf planets by astronomers as well.

90482 Orcus, and his moon Vanth shines at magnitude +19.1 between Hydra, the Sea Monster and Serpens the Snake.

50000 Quaoar,and his moon Waywot shines at magnitude +18.6 in Ophiucus the Serpent Bearer,

90377 Sedna, the coldest, and at one time, the most distant known place in the Solar System, glows faintly at magnitude +20.9 in Taurus the Bull.

225088 Gonggong, and his moon Xiangli glows dimly at +21.5 magnitude in Aquarius the Water Bearer.

Unnamed Dwarf Planet 2014 UZ224, nicknamed “DeeDee” for “Distant Dwarf” is 8.5 billion miles from the Sun, at magnitude +23.1 in Eridanus the River.

Currently the most distant observable known object in the Solar System, an asteroid unofficially called Asteroid 2018 AG37, and nicknamed FarFarOut, glows at a barely detectable +25.5 magnitude in Lynx.

FarFarOut is currently 12,396,145, 283 miles or in Light Time, 18 hours, 29 minutes and 4.8 seconds from Earth.

The most distant man-made object, Voyager 1, still operating after 45 years, 11 months and 15 days is 14,930,222,731 miles, or in Light Time, 22 hours, 15 minutes and 48 Seconds from Earth as of 3:05 PM, August 20, 2023, sailing 38,027 miles per hour through Ophiuchus the Serpent Bearer.

There are 1,301,184 known asteroids as of August 20, 2023 per NASA.

5496 planets beyond our solar system have now been confirmed as of August 10, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/.

Last Quarter Moon, or when the moon has only the Eastern side illuminated, will occur September 6 at 5:21 PM CDT or 10:21 UTC.

During a Quarter Moon the Moon’s magnitude is -10.0.

The Moon will be at Apogee or its farthest distance from Earth on September 12, when she will be 252,456 miles from Earth.

New Moon occurs September 14 at 8:39 CDT PM or 1:39 UTC on September 15, when the Moon will on the same side of the Earth as the Sun and will not be visible in the night sky. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

First Quarter Moon, or when the moon has only the Western side illuminated, will occur September 22 at 2:31 PM or 7:31 UTC.

Fall begins at Autumnal Equinox on September 23 at 1:50 AM CDT or 6:50 UTC, when the Sun crosses directly over the equator and night and day is approximately the same length throughout the world. For the Southern Hemisphere it is Vernal Equinox, the first day of Spring.

One term that occasionally pops up is “equinoctial storms”. Which are severe storms in North America and the UK that supposedly accompany the vernal and autumnal equinoxes. Where this belief originated is obscure. Some say perhaps from the 1700’s when sailors were greeted by West Indies hurricanes, or due to the coincidence of the first fall severe storms sometimes coming in the latter half of September. At any rate, statistics show no evidence to support the belief.

On this date, if there is sufficient solar activity, and you are away from city lights, the aurora may possibly be seen, as the Equinox dates are the two most favored times of the year for auroral sightings.

At this time of year, the interplanetary magnetic field (IMF) can link up with Earth’s magnetic field, prying open cracks. Solar wind pours in to fuel displays of the aurora borealis with no geomagnetic storm required. Researchers call this the “Russell-McPherron” effect after the space physicists who first described it in the 1970s.

The Moon will be at Perigee or her closest approach to Earth on September 28, when she will be 223,638 miles from Earth.

September’s Full Moon will occur September 29 at 4:59 AM CDT or 09:59 UTC.

The Moon will be located on the opposite side of the Earth as the Sun and its face will be fully illuminated. This full moon was known by early Native American tribes as the “Corn Moon” because the corn is harvested around this time of year.

This moon is also known as the Harvest Moon. The Harvest Moon is the full moon that occurs closest to the September equinox each year.

The name “Harvest Moon” dates from the time before electricity, when farmers depended on the Moon’s light to harvest their crops late into the night. The Harvest Moon was especially important since it coincided with the largest harvest of the year.

This is the last of four Supermoons for 2023. The Moon will be near its closest approach to the Earth and may look slightly larger and brighter than usual.

During a Full Moon, the Moon’s magnitude is -12.7.

Comet C/2023 P1 (Nishimura) is a long-period comet which was discovered by amateur astronomer Hideo Nishimura on 12 August 2023.

It is possible that it could be bright enough to be observed with binoculars in the first days of September before sunrise.

Comets are notoriously unpredictable, with faint ones flaring brilliantly, anticipated bright ones never brightening at all or being melted into rubble by the Sun.

If you want to see this new comet, you’ll need to rise early in the morning, between one and half to two hours before sunrise. You’ll also need good binoculars, say a 7 X 35 mm pair, but, not a telescope, as binoculars give you maximum light gathering capability, and two light detectors – your eyes – where telescopes overmagnify and lose definition when looking at defuse objects and provide one eyes worth of visual data.

You will need to find a dark sky, well away from any bright lights and a clear and unobstructed view of the east-northeast sky.

At the beginning of the month, it will be tracking through the faint stars of Cancer, The Crab and moving into Leo, The Lion across a star grouping known as “The Sickle” – the backward question mark star pattern marking the head and mane of Leo, The Lion.

He will be low above the horizon, and lowering each passing day. He will brighten to magnitude 5, just borderline naked eye visibility, but will be only 10°, or one outstretched fist width, above the horizon as the twilight sky brightens. He will then drop into the Sun’s glare, and if he survives the passage near the Sun, he will reappear in the evening sky, but, only in the skies of the Southern Hemisphere.

High in the Southern night sky an asterism or a group of stars appearing clustered together, but not actually gravitationally bound, will be seen that resembles a teapot. This is the Teapot of Sagittarius.

To the naked eye, the Teapot is roughly the size of your fist at arm’s length. Above the spout of the Teapot lies a band of light, emerging like steam from the spout of the Teapot, which is the Large Sagittarius Star Cloud. A pair of binoculars will reveal a sea of stars and faint grayish patches, the largest of which is the Lagoon Nebula. When you look upon these nebulae you are seeing stars in the process of being born.

The spout, which is tilting and pouring to the right, also points towards the galactic center of the Milky Way, located just beyond the Large Sagittarius Star cloud, but largely hidden by the dust clouds, which lie along the plane of the Sagittarius arm of the galaxy.

While we sweat through Summer, do you want at sneak peek at the Winter sky? Step out before the first light of dawn, and the sky displays the same starry panorama it does at dinnertime around New Year’s. With Orion the Hunter striding up in the southeast, Taurus the Bull with Aldebaran and then the Pleiades high above it. Sirius the Dog Star sparkles far down below Orion, and Gemini The Twins are lying on their sides well up in the east, left of Orion.

Hi everyone,

I hope this finds you safe and well as we bake and broil in this miserable heat. The good news is that in just a little over a month the heat and humidity will begin it’s retreat towards the tropical realms from whence it came and in about 6 months we will be griping and wishing we could borrow one of these days for a welcomed winter thaw.

Until then hug an air conditioner, remember to stay hydrated and don’t cook the doggy by walking him in this giant toaster oven that we find ourselves in.

Our next ALERT meeting will be on August 8, at the NWS Forecast Office in Calera, (which has good air conditioning).

How Low Can You Go?

I have always loved radio and radio technology. One could say, with apologies to the streaming service, that “I heart radio”. My fond heartedness stretches almost as long as my interest in astronomy, which began at age 5, as I looked through my older sister’s science book and marveled at the pictures it contained.

Now and then I have heard, when speaking of radio receivers, of wishing that one had a radio reaching from “DC to Daylight.” And, while such a mythological beast does not yet exist, we edge closer and closer to it with each decade.

Current radio technology allows access from 3 Hz to 10 – 30 THz. At that 30 THz point there is a gap called the “Terahertz Gap” for which the practical technologies for generating and detecting the radiation in the electromagnetic spectrum from that point to the infrared light spectrum does not yet exist.

This realm is also considered the far infrared light spectrum, which stretches from roughly 300 GHz to 30 THz.

Above this is the mid infrared, from 30 GHz to 120 THZ and near infrared region from 120 THz to 400 THZ. Then we reach visible light, with red 400 to 480 THz, orange 480 to 510 THz, yellow 510 – 530 THz, green 530 – 600 THz, cyan 600 – 620 THz, blue 620 – 670 THz and violet 670 – 790 THz. Then comes ultraviolet, then x-ray and finally gamma ray radiation.

The main limiting factor that causes the Terahertz gap is, except for some experimental devices, the Earth’s atmosphere.

As the radio frequency increases above 30 GHz, the Earth’s atmospheric gases absorb increasing amounts of RF power, and the power of all radio waves decreases exponentially with distance from the transmitting antenna.

At 30 GHz, useful communication is limited to about around .6 miles or 1 km, and decreases as the frequency increases so that when you reach the realm 300 GHz, the radio waves are attenuated to zero within a few yards, so the atmosphere is essentially opaque to radio signals.

In the vacuum of space, this would not be a problem and perhaps some day these frequencies will be used by space explorers and outposts.

Meanwhile here on Earth, as technology progresses, the Terahertz Gap, is closing, and some day it will be overcome, just as the 200 meter radio frequency limit was.

100 years ago, the frequencies above 200 meters or 1.5 MHz or 1500 kHz we’re considered “useless” and hams were consigned to them to cure their propensity for interfering with marine and broadcast stations.

Then hams discovered that worldwide communications we’re possible on these useless higher frequencies and short wave radio was born.

But, that’s how high can you go and the question was how low you can really go on the radio dial?

Low frequency oscillations related to the Earth’s magnetosphere occur below 3 Hz, in the Ultra Low Frequency range or ULF.

Extreme Low Frequency range or ELF stretches from 3 to 30 Hz.

ELF signals can penetrate seawater and the attenuation of ELF waves is so low that they can travel completely around the Earth several times before significantly decaying, and waves radiated from a source in opposite directions circumnavigating the Earth on a great circle path will interfere with each other.

The lowest frequencies currently in use are in the SLF or Super Low Frequency realm from 30 HZ to 300 Hz and are used to signal submerged submarines.

At these low frequencies (which are commonly, if mistakenly referred to as ELF) the signal bandwidth is so very small that voice communications are not possible and only short, coded text messages at a very low data rate are possible. These messages are used to instruct submarines to rise to the surface to receive longer operational orders by ordinary radio or satellite communication.

The US Navy operated a system called Project ELF from 1989 to 2004 using two linked transmitters at Clam Lake Wisconsin & Republic Michigan.

The Clam Lake facility had two 14 mile transmission line antennas, called ground dipoles, in the shape of a cross, with the transmitting station at their intersection.

The Republic facility consisted of three transmission line antennas, two of which were 14 miles long and one 28 miles long in the shape of the letter “F”. The shape was not significant, but was dictated by land availability.

The system transmitted at 76 Hz, 16 Hz above the North American power line frequency, with an alternate capability at 45 Hz and used a combined power of 2.6 megawatts.

The system transmitted continuously, 24 hours a day, sending an “idle” message when it was not being used, so that submarines could verify they were within communication range.

The system was controversial, especially with environmentalists and protesters, who cut down the transmission line poles five times, briefly interrupting operations.

In 2004 the Navy shut down both transmitters, explaining that the Very Low Frequency, VLF, communication systems had improved to the point that the ELF system was unnecessary.

The lowest known confirmed manmade signal to be received is an experimental Russian signal for “geophysical applications” transmitted at 12 kHz on the Kola Peninsula southeast of Murmansk.

The Russian Navy currently uses a transmitter at 82 Hz called ZEUS to communicate with its submarines. The transmitter is 19 miles southeast of Murmansk on the Kola peninsula in northern Russia, and produces an estimated radiated power between 10 & 14 megawatts, which if accurate would make it the most powerful transmitter in Europe.

The Indian Navy operates an ELF transmitter at the INS Kattabomman Naval Base in Tamil Nadu to communicate with its Arihant & Akula Class submarines.

China recently built an ELF transmitter complex with an antenna said to be five times the size of New York City. It is thought to be in the Dabie Mountains, a protected reserve that spans the Hubei, Anhui and Henan Provinces, 620 miles south of Beijing. It’s antenna is in the shape of a cross 62 miles long and wide.

The frequency of the Indian and Chines transmitters is बेअत्स मे and 我不知道.

The lowest frequency stations I ever received were the now defunct US Omega navigation beacons on 10.2, 11.33 and 13.6 kHz and the still operational Russian Alpha beacons on 11.90 12.64 and 12.88 kHz.

The equipment I used was a Radio Shack DX-300 receiver (one of the few receivers that reach below 100 kHz), a homemade 80 turn loop antenna and an unbelievably long antenna strung back and forth along the top of a fence. Maybe 1,000 of wire. I also made a homebrew low pass filter to silence the interference from broadcast stations and crude tuner antenna tuner out of spare parts and poking and praying. The receiver could be coaxed down to 8 kHz.

Today there is a problem with modern receivers and VLF reception. I have a Yaesu FT-450 and a Kenwood TS-570D and while both will receive in the VLF range down to 30 kHz, both also kick in a 20 db attenuator when you go below 1.800 MHz, which effectively kills their ability to receive distant stations below 160 meters. On the other hand, my Yaesu FT-817 doesn’t have this attenuator, so you can still enjoy AM and VLF DXing, albeit only to 100 kHz.

The VLF world is a weird stretch of radio spectrum. There are natural signals you will occasionally hear including the “dawn chorus”. A sound appearing at dawn which resemble the sound of birds at dawn, the cause of which is a bunch of mumbo jumbo related to the electrons being injected into the Earth’s magnetosphere by solar storms.

You may also hear a “whistler”, which sounds like someone whistling to get your attention, caused by static or “sferics” from thunderstorms in the southern hemisphere following the lines of the Earth’s magnetic field from storms located at the same latitude and longitude in South America. Static from the Amazon, in our case.

As you go higher in frequency you will on occasion hear teletype from naval bases to submarines and other military users.

81.000 kHz GYN2 Inskip, UK
100.00 kHz LORAN-C Navigation System

As with all radio signals, there are no guarantees you will hear any of the above just when you want to. Patience is the key.

Note that WWVB at 60 kHz is a non-voice digital signal, quite unlike WWV & WWVH. It is the signal used to synch clocks and other devices. It sounds like a carrier with “occasional “dit” sounds.

As to LORAN-C, in May 2009 the Obama Administration declared the system obsolete and announced plans to terminate it. Some countries opted to continue the system as a backup to the GPS, in case it was disabled, either due to natural causes or an act of war. Other countries dropped the system. So, you may or may not hear a thing. If you tune to 100 kHz and hear a sound like dice being shaken in a Yahtzee cup, you are hearing LORAN-C.

It is quite different from the ear shattering buzz saw sound of the old LORAN-A system that transmitted from 1850 – 1950 kHz covering most of the 160 meter ham band. The 160 meter ham band was a secondary allocation, LORAN-C was primary and hams we’re at reduced power and on a non-interfering basis.

I can clearly recall the sound – like a dozen giant cicadas droning in slow motion.

Thankfully for hams that ended in North America on December 31, 1980.

So, there you have the radio world from 0 to 100 kHz.

If you have the equipment, give it a try. You never know what you will hear!

Mark’s Almanac

August was originally named “Sextilis”, the sixth Roman month. It was renamed August in honor of Caesar Augustus and lengthened to 31 days, to equal Julius Caesar’s month of July.

August is hot and humid and summer temperatures remain at or near their summer peak.

The rapid vegetation growth of spring is over, and, since conditions are now perfect for the growth of mold, fungi & germs, plants have a “used” look, which is enhanced if rainfall is scarce.

In August the choir of cicadas whine in the afternoon & towards the end of the month the big Yellow Sulphur Butterflies will begin heading to the South-Southeast, giving hints of their soon upcoming fall migration & cats will begin to hint of growing their winter coats.

Hurricane breeding grounds in August are the Atlantic, with Low Latitude “Cape Verde” storms forming off Africa crossing the Ocean and either threatening the Eastern Seaboard or striking the Leeward Islands, entering the Caribbean and then striking the Yucatan, or the Western or Northern Gulf coast. Breeding grounds also include the Caribbean and Gulf of Mexico.

August is second only to September in the number of Tropical Storms and Hurricanes. From 1851 to 2022 there have been 402 Tropical Storms and 252 Hurricanes, 82 of which made landfall in the United States, the most notable storms being Hurricanes Camille, Katrina and Ida in 1969, 2005 and 2021, which devastated Mississippi and Louisiana and Hurricane Andrew which ravaged South Florida in 1992.

21% of a year’s Hurricanes occur in August, however, 85 to 95% of land falling Hurricanes have not occurred by August 15.

Days grow shorter as the Sun’s angle above the noonday horizon steadily decreases from 74.4 degrees at the beginning of the month to 65.0 degrees at the month’s end. Daylight decreases from 13 hours 48 minutes on August 1 to 12 hours 54 minutes on August 31.

Sunrise and sunset times for Birmingham are:

August 1 Sunrise 6:00 AM Sunset 7:47 PM
August 15 Sunrise 6:09 AM Sunset 7:34 PM
August 31 Sunrise 6:20 AM Sunset 7:14 PM

Looking skyward, the Sun, magnitude -26.7 is in Cancer, The Crab.

Mercury, magnitude -0.3 in Leo, The Lion, is lost in the glow of the Sun this August.

Venus, magnitude -4.6 in Leo, The Lion, is lost in the glow of the Sun. She will pass between the Sun and the Earth, or reach “Inferior Conjunction” on August 13.

She by months end she will reemerge into the morning sky rising around 4:30 AM, almost 2 hours before the Sun.

Earth, magnitude -4.0 as viewed from the Sun, and her Moon is in the constellation Capricornus, The Sea Goat.

Mars, magnitude +1.7, with his Moons Phobos and Deimos in Leo, The Lion, is lost in the glow of the Sun.

Dwarf Planet Ceres, magnitude 8.8, is in Virgo, The Virgin.

Jupiter, magnitude –2.3, and his 95 moons and (invisible from Earth) ring, in Aries, The Ram, is an early morning object, rising at the first of the month, around midnight and reaching 64° above the southeast horizon before fading from view as dawn breaks just before 6 AM.

By months end he rises around 11 PM and reaches 71° above the eastern horizon around 5 AM and fades into the dawn an hour later.

Saturn, magnitude +0.6, and his 146 moons and extensive debris ring system, is in Aquarius, The Water Bearer,

He is a morning object, becoming visible around 10 PM and reaching his highest altitude of 45° above the southern horizon just after 2:30 AM, and fading from view at dawn.

He rises earlier and earlier as the month progresses and by months end he will rise at 8 PM and reach high highest point 44° above the southern horizon just after midnight and fades from view at sunrise.

He will reach peak brightness as he reaches “Opposition” or lies directly opposite of the Sun at 3 AM on August 27.

Uranus, magnitude +5.9, and his 27 moons and ring, in Aries, The Ram, has emerged from behind the sun and becomes visible half past midnight and reaches an altitude of 51° above the eastern horizon before fading into the dawn.

By month end he rises around 10:30 PM, reaching an altitude of 74° above the southern horizon before fading as dawn breaks.

Neptune, magnitude 7.7, and his 14 moons and ring, is in Pisces, The Fish, is a morning object becoming accessible using a telescope at midnight at an altitude of 21° above the eastern horizon & reaching his highest point at 54° above the southern horizon around 4 AM and will only drop to 52° as twilight fades in.

By months end he will become accessible around 10 PM and will reach high highest point in the sky around 2 AM, 53° above the southern horizon, and finally disappearing from view three hours later in the twilight.

Dwarf Planet Pluto, with his five moons shines at a dim +14.4 in Sagittarius, The Archer.

Dwarf Planet 136108 Haumea, her ring and moons Hiʻiaka and Namaka, shines at a faint magnitude of +17.4 in Bootes the Herdsman

Dwarf Planet 136472 Makemake with his moon S/2015 (136472) 1, nicknamed MK1 by the discovery team, shines faintly at magnitude +17.2 in Coma Berenices.

Dwarf Planet 136199 Eris and her moon Dysnomia, originally referred to as Xena and Gabrielle, is barely visible in the most powerful telescopes at magnitude +18.7 in Cetus the Sea Monster.

At least five additional bodies with the preliminary criteria for identifying dwarf planets, and though not “officially” declared as such, are generally called dwarf planets by astronomers as well.

90482 Orcus, and his moon Vanth shines at magnitude +19.1 between Hydra, the Sea Monster and Serpens the Snake.

50000 Quaoar,and his moon Waywot shines at magnitude +18.6 in Ophiucus the Serpent Bearer,

90377 Sedna, the coldest, and at one time, the most distant known place in the Solar System, glows faintly at magnitude +20.9 in Taurus the Bull.

225088 Gonggong, and his moon Xiangli glows dimly at +21.5 magnitude in Aquarius the Water Bearer.

Unnamed Dwarf Planet 2014 UZ224, nicknamed “DeeDee” for “Distant Dwarf” is 8.5 billion miles from the Sun, at magnitude +23.1 in Eridanus the River.

Currently the most distant observable known object in the Solar System, an asteroid unofficially called Asteroid 2018 AG37, and nicknamed FarFarOut, glows at a barely detectable +25.5 magnitude in Lynx.

FarFarOut is currently 12,405,728,855 miles or in Light Time, 18 hours, 29 minutes and 56.3561 seconds from Earth.

The most distant man-made object, Voyager 1, still operating after 45 years, 10 months and 17 days is 14,872,856,766 miles, or in Light Time, 22 hours, 10 minutes and 40 Seconds from Earth as of 2:13 PM, July 22, 2023, sailing 38,027 miles per hour through Ophiuchus the Serpent Bearer.

There are 1,299,492 known asteroids as of July 22, per NASA.

5470 planets beyond our solar system have now been confirmed as of July 11, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/.

August’s Full Moon will occur August 1 at 1:33 PM or 18:33 UTC. August’s Full Moon was called “Fruit Moon” in Cherokee Folklore, “Women’s Moon” among the Choctaw, “Sturgeon Moon” by the Algonquin because the large sturgeon fish of the Great Lakes and other major lakes were more easily caught at this time of year. This moon has also been known as the Green Corn Moon and the Grain Moon and at one time was called “Dog Days Moon” by the Colonial Americans.

This is the second of four Supermoons for 2023. The Moon will be near its closest approach to the Earth and may look slightly larger and brighter than usual.

During a Full Moon the Moon’s magnitude is -12.7.

The Moon will be at Perigee or its closest approach to Earth on August 1, when she will be 222,022 miles from Earth.

Last Quarter Moon, or when the moon has only the Eastern side illuminated, will occur August 8 at 5:28 AM CDT or 10:28 UTC.

During the Quarter Moon the Moon’s magnitude is -10.0.

The Perseid Meteor Shower peaks on the night of August 12 & 13, with 50 to 60 meteors per hour. This shower, produce by debris from Comet Swift-Tuttle, which was discovered in 1862, ranks as the best of the best, famous for producing bright meteors. The shower runs annually from July 17 to August 24. It peaks this year on the night of August 12 and the morning of August 13.

The crescent moon should not be too much of a problem this year. Skies should still be dark enough for a good show. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Perseus, but can appear anywhere in the sky.

New Moon will occur at 4:39 AM CDT or 09:39 UTC on August 16. The Moon will be located on the same side of the Earth as the Sun and will not be visible in the night sky. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

The moon will be at Apogee or its farthest distance from Earth on August 16, when she will be 252,671 miles from Earth.

First Quarter Moon, or when the moon has only the Western side illuminated, will occur August 24 at 4:57 AM CDT or 9:57 UTC.

On August 24 a rare event will occur as the Moon passes in front of the bright star Antares
in the constellation Scorpius.

This event, called an “Occultation” will be visible from the contiguous United States, Mexico and Canada.

The occultation will be visible from Birmingham beginning with the disappearance of Antares behind the Moon at 21:47 CDT or 02:47 UTC August 25 in the south-western sky at an altitude of 18.6°, and ends with the star’s reappearance at 22:37 CDT or 3:37 UTC August 24 at an altitude of 11.5 degrees.

The astronomical term “Occultation” is defined by Merriam-Webster as “Middle English occultacion, borrowed from Latin occultātiōn-, occultātiō “concealment, interruption of light from a celestial body,” from occultāre “to prevent from being seen, conceal, keep secret” + -tiōn- -tiō, suffix of verbal action”. It has nothing to do with the “occult” or any other type of witchy poo type of stuff.

Once in a blue moon you get a Blue Moon, one definition of which is “two full moons in a calendar month”.

On August 30 we will have a second Full Moon, which qualifies as a Blue Moon, which is also the third Supermoon of 2023.

This phase will occur 8:35 PM CDT or 01:35 UTC.

As with the Supermoon on August 1, the Moon will be near its closest approach to the Earth and may look slightly larger and brighter than usual.

NEWSFLASH!!!

“SMALL ASTEROID CAPTURED HOURS PRIOR TO EARTH IMPACT” says the various blurbs flashing on my laptop.

Hmmm….I thought. One could think that an inbound asteroid was intercepted and “captured” before impact. Some hyperdynamicthermofubbulator they’ve kept secret just grabbed hold of the sucker and captured it, saving the planet, one could conclude. If such technology suddenly appeared.

So, I naturally was curious.

On March 11, 2022, “Apollo Near-Earth Asteroid” 2022 EB5, a small 2 meter or 6.56 foot asteroid struck the Earth’s atmosphere at 11 miles per second and promptly disintegrated over the Arctic Ocean southwest of the Norwegian island Jan Mayen.

It produced a 4 kiloton fireball that was detected in Greenland and Norway and a bright flash was seen in Iceland.

So….it burned up in the atmosphere and did not “impact” the Earth.

It wasn’t exactly “captured” in the “grabbed the sucker” sense either.

Astronomer Krisztián Sárneczky at Konkoly Observatory’s Piszkéstető Station in Mátra Mountains, Hungary photographed the object about two hours before impact.

So, it was “captured” on film.

I guess “Asteroid photographed before burning up over Arctic” just isn’t dramatic enough.

Apollo Class Asteroids are a group of Near Earth, Earth orbit crossing asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s.

The largest of the 17,540 Apollos, is 1866 Sisyphus. A 4.35 mile rock which sport its own a tiny moon.

1866 Sisyphus is believed to be similar size to the Chicxulub object whose impact in the Yucatan is believed to have caused the Cretaceous–Paleogene extinction event, a sudden mass extinction of three-quarters of the plant and animal species on Earth, including all non-avian dinosaurs, approximately 66 million years ago.

There are also other Earth orbit crossing asteroids, namely 2,445 Aten asteroids.

Other Near Earth Asteroids are the 30 odd Atira Class Asteroids, which orbit just inside the Earth’s orbit and the 11,232 Amor Class Asteroids, which orbit just beyond the Earth’s orbit.

Reader Feedback

On occasion I receive feedback from our readers. I appreciate the kind words and suggestions I receive, as everyone needs positive affirmation now and then, and because it confirms that someone is actually reading this rag.

Various comments I have heard along the way are “it’s long, that’s for sure” and “the almanac is my favorite part”, both points I agree with, by the way.

I enjoy researching the almanac and I can be long winded and run off at the keyboard at times.

Occasional questions are posed, and I wish to answer a couple of them.

How Hurricane Outlooks Are Made

In the May & June ALERT newsletters I shared the 2023 Hurricane Outlooks issued by Colorado State University, Accuweather & NOAA.

A reader asked the question “How are these outlooks made?”

First I’ll mention that these “outlooks” are not “landfall forecasts”. Using NOAA as an example, NOAA does not make seasonal hurricane landfall predictions, for hurricane landfalls are largely determined by the weather patterns in place as the hurricane approaches, and those patterns are only predictable when the storm is within several days of making landfall. Such precision is an impossibility. There are simply too many variables involved.

The outlook which is issued is a probabilistic outlook of the “likely” ranges of activity that has a “certain likelihood of occurring” given the hints, clues and conditions that are being observed or are climatologically trending towards.

The seasonal activity is expected to fall within these ranges in 7 out of 10 seasons based on previous seasons with similar climate conditions factoring in uncertainties.

They do not represent the total possible ranges of activity seen in past similar years, but the most likely and logical, with the realization that Mother Nature can be a cantankerous old heifer, throwing a monkey wrench into the works.

When looking at the various, often conflicting factors, the first thing forecasters look at is the equatorial Pacific Ocean.

Do they see a La Niña, El Niño or neither?

During La Niña, the interaction between the Pacific Ocean and the atmosphere above cause strong winds to push the warm water at the ocean’s surface westward from South America to Indonesia. As the warm water moves west, colder deeper water rises to the surface near the coast of South America. This makes the water in the Pacific Ocean near the equator a 4° to 6° F below average.

This small change in the ocean’s temperature can affect weather all over the world.

Rain clouds normally form over warm ocean water. La Niña blows this warm water to the western Pacific. This means that places like Indonesia and Australia can get much more rain than usual. However, the cold water in the eastern Pacific causes less rain clouds to form on the eastern side of the Pacific.

La Niña can help shift the track of the jet stream and consequently how storm systems move across the continental United States.

While wetter than average conditions develop across portions of the northern U.S, namely the Pacific Northwest, northern Rockies, Great Lakes, Ohio Valley and western Alaska, the
subtropical jet stream shifts to the north, moving the storm tracks to northern Alabama and Georgia, increasing the likelihood of tornadoes and severe weather, while leaving Florida sunnier and drier than usual.

In the tropics La Niña causes stronger vertical wind shear which suppresses hurricane formation in the eastern Pacific, while in tropical Atlantic weaker wind shear and trade winds and greater atmospheric instability enhances tropical activity.

When La Niña’s mischievous bother, El Niño appears, the effects are opposite, bringing ocean temperatures of 4° to 6° F above average between the International Date Line and the west coast of South America.

Atmospheric pressure increases near Indonesia and in the western Pacific and decreases in the eastern Pacific. Pressure changes lead to the subtropical jet stream moving into Florida, southern Georgia, and Alabama, steering cloudy, rain-bearing systems into the region in winter and an increasing likelihood of tornadoes and severe weather in the Florida peninsula.

In the tropics El Niño causes weaker vertical wind shear which enhances hurricane formation in the eastern Pacific, while in tropical Atlantic stronger vertical wind shear and trade winds and greater atmospheric stability suppresses hurricane formation in the tropical Atlantic.

La Niña can last 1 to 3 years, while El Niño lasts no more than 1 year.

During the past three hurricane seasons we have seen La Niña, but NOAA’s Climate Prediction Center give a 93% chance that an El Niño will be in place by August through October, the heart of the Atlantic hurricane season.

This tends to limit the number and intensity of storms and hurricanes, with fewer Gulf of Mexico storms and more storms to either curl north, then northeast out into the open Atlantic Ocean or to impact parts of the East Coast.

So, based on this alone we should have a fairly docile season.

But there is a hitch – the Atlantic Ocean is warm. Very warm, which could lessen or counteract the effect of El Niño.

Hurricane season generally begins when water temperatures reach roughly 80 degrees, which usually occurs between June 1 and Nov. 30. Much of the Atlantic basin is warmer than usual for spring, particularly in the Gulf of Mexico, off the Southeast coast and in the eastern Atlantic.

The deeper and warmer ocean water is, the stronger a hurricane can become.

Currently temperatures closely resemble those prior to the active 2020 hurricane season, one of the most active hurricane seasons on record with nearly every community in the coastal United States experiencing the effects of a tropical storm or hurricane.

Will the warmer temperatures defeat El Niño? Only time will tell.

Other uncertainties include the fact that predicting these El Niño and La Niña events, also called the El Niño-Southern Oscillation, or ENSO is an inexact science, with skills that are continuously evolving. This skill is limited, as is the skill of predicting sea-surface temperatures, vertical wind shear, moisture, atmospheric stability, and other factors known to influence overall seasonal hurricane activity.

So, the outlooks by NOAA and others are a balance of competing factors, based on, to quote NOAA:

“These predictions are based on extensive monitoring, analysis, research activities, a suite of statistical prediction tools, and dynamical models. The dynamical model predictions come from the NOAA Climate Forecast System (CFS), NOAA Geophysical Fluid Dynamics Lab (GFDL) HiFLOR-S and SPEAR-MED models, the North American Multi-Model Ensemble (NMME), the United Kingdom Met Office (UKMET) GloSea6 model, and the European Centre for Medium-Range Weather Forecasting (ECMWF) Seas5 model.”

It’s a best guess, with the best information and interpretation that science currently provides.

While we are delving in alphabet soup, let me lay this on you.

Recently on social media two nets we’re advertised.

Both of these postings have something in common. Namely I don’t have a solitary clue as to what they are talking about or how to participate.

One of the suggestions I have received, and I think it is a good one, especially since ALERT utilizes some of these modes, is to explain how these modes work.

Here is the problem. I am an old goat.

I can click a Morse code key and press microphone push to talk connected to a radio, which uses an antenna that could easily pass for a clothesline. And, if I am lucky, some hapless fool somewhere on the globe will hear my anemic signal drifting in somewhere in the static.

As for the modes mentioned above, I am clueless.

So, if you happen to understand any of the gibberish I have just typed, help us out by writing a plain English article explaining all this gobbledygook for old goats like me, for whom Google has not been our friend.

What are these modes? How do they work? Which ones are popular locally?
What resources and equipment does one need? Are they worth the effort and expense?

Your input will be appreciated by inquiring goats, both old and new, who really do want to know.

Thanks!

Mark’s Almanac

Originally called “Quintilis”, the fifth Roman month, Quintilis was renamed “July” in 44 BC in honor of Julius Caesar.
July is miserably hot, as land temperatures reach their peaks in late July through early August – the Dog Days of Summer.

The Old Farmer’s Almanac lists the traditional period of the Dog Days as the 40 days beginning July 3 and ending August 11.

The Romans on the other hand said that the Dog Days ran from July 24 through August 24, or, alternatively, from July 23 through August 23, coinciding with the Sun and the Dog Star Sirius rising at the same time & their combined heat supposedly adding to the summer misery.

As you endure this heat, remember to drink lots of fluids, hug the shade & avoid the afternoon sun.

Also please resist the temptation to take Fido for a walk during the heat of the day. Remember that the “official” temperature readings are taken 6 feet above ground level. It’s much, much hotter on the ground where Fido & Puss must walk with bare paws, where it could easily be 150 degrees.

Before taking Muttley for a walk, place your hand on the pavement and see how hot it is. If it’s miserable to you, it will be miserable to him also. Just walk him in the morning or wait until the sun is setting and it cools off to a tolerable level and try to stick to grassy areas. Then go have a good time together.

The last week of July is usually the hottest week of the year. Tropical conditions are dominant, with conditions similar to that of the Amazon Valley.

This is the time to test the “Brown Grass Theory”. According to this theory, if the grass remains green the temperature will probably not reach 100, but, if the grass turns brown, get set for triple digits. This is a local Birmingham rule, which the Old Timers at the Birmingham NWS, such as Frank Makosky and J.B Elliott used for years.

In July the least rainfall falls in the Northern Hemisphere.

Tornado activity drops sharply, with a 47% decrease nationwide. July has an average of 103 tornadoes.

Hurricane activity increases, but major hurricanes are not yet frequent. By months end, one hurricane will have occurred. Seven percent of a year’s hurricane total occurs in July.

July Tropical Cyclone Breeding Grounds

Long track hurricanes are possible, forming off the African coast and crossing the Atlantic, either to threaten the US East Coast, then eventually veering off towards Bermuda. Or in the case of “Low Latitude” storms, cross the Atlantic, strike the Leeward Islands; enter the Caribbean and then striking the Yucatan, or the Western or Northern Gulf coast.

From 1851 to 2022 there have been 130 Tropical Storms and 61 Hurricanes, 29 of which made landfall in the United States.

Among notable storms are 2005’s Hurricane Emily, the only Category 5 storm to form in July, reaching 160 MPH and striking Mexico.

Hurricane Bertha, a 125 MPH storm holds the record for the longest lifespan for a July hurricane, churning for 17 days.

Days grow shorter as the Sun’s angle above the noonday horizon decreases from 79.6 degrees at the beginning of the month to 74.7 degrees at the month’s end. Daylight decreases from 14 hours 20 minutes on July 1 to 13 hours 49 minutes on July 31.

Sunrise and sunset times for Birmingham are:

July 1 Sunrise 5:41 AM Sunset 8:01 PM
July 15 Sunrise 5:48 AM Sunset 7:58 PM
July 31 Sunrise 5:59 AM Sunset 7:48 PM

Looking skyward, the Sun, magnitude -26.7 is in Gemini.

At the beginning of the month Mercury, magnitude -1.6 in Taurus, The Bull, is lost in the glow of the Sun.

Venus, the brilliant “Evening Star, shines at magnitude -4.6 in Leo, The Lion, dominates the evening sky rising a little after 8:00 PM, 25° above the western horizon, as dusk fades to darkness and setting around 10:20 PM.

As the month progresses she will sink lower and lower each night until finally disappearing from the night sky on the 25th.

Venus will pass 3.6° north of Mars, or be in a “quasi-conjunction”, on July 1, at 2:48 AM or 06:48
UTC.

If two planets come to within 5° or less of one another but, don’t actually pass each other, (which is a conjunction) it’s called a “quasi-conjunction”.

In this case he two worlds won’t pass each other, but, will approach each other and then as the weeks go by slowly drift apart,

For perspective, a Full Moon is 0.5° wide, so they will be 7 Full Moons apart.

She will pass 1.7° South of the star Regulus on Leo on July 16.

In a telescope she is a brilliant thin crescent.

Earth, magnitude -4.0 as viewed from the Sun, is in the constellation Sagittarius, The Archer.

Earth will reach her farthest distance from the Sun or Aphelion on July 6 at 3:06 PM CDT or 20:06
UTC, when the distance from the Sun’s center to Earth’s center will be 94,506,364 miles from our home star, as she and the Moon wobble through space, the Moon tugging on the Earth like an unruly pup on a leash.

Mars, magnitude +0.7, with his Moons Phobos and Deimos are in Leo, The Lion, is an early evening object, becoming visible just before 9:00 PM, 21° above the western horizon, as dusk fades to darkness and setting around 10:40 PM.

Like Venus, as the month progresses he will sink lower and lower each night finally disappearing from the night sky on the 22nd.

Dwarf Planet Ceres, magnitude 8.5, is in Virgo, The Virgin.

Jupiter, magnitude –2.2, and his 95 moons and (invisible from Earth) ring, is in Aries, The Ram, riseing in the early morning sky around 2:00 AM, 40° above the eastern horizon, 3 hours and 40 minutes before the Sun, and fading from view at sunrise.

He gains altitude each night and rising ever earlier and by the end of the month rises a little after 1:00 AM, when he will be 64° above the south-eastern horizon, fading from view at dawn.

Saturn, magnitude +0.8, and his 146 moons and extensive debris ring system, is in Aquarius, The Water Bearer, as a morning object. He becomes visible around midnight, low in the eastern sky, 11°, and reaches his highest point in the sky just before 5:00 AM, 45° above the southern horizon, just before fading into the dawn.

As the month progresses he will rise earlier and earlier and by months end will rise just after 10:00 PM and reaching his highest point in the sky just before 3:00 AM, 45° above the southern horizon and fades from view at sunrise.

Uranus, magnitude +5.9, and his 27 moons and ring, in Aries, The Ram, has emerged from behind the sun and rises 2:20 AM, 3 hours before the Sun, reaching an altitude of 22° above the eastern horizon before fading from view at dawn.

By months end he will rise just after midnight and reach an altitude of 50° above the eastern horizon before fading into the dawn.

Neptune, magnitude 7.8, and his 14 moons and ring, is in Pisces, The Fish, having emerged from behind the Sun, and is a morning object rising at midnight and reaching an altitude of 41° above the south-eastern horizon before fading into the dawn.

By months end he will becomes visible (in telescopes) around midnight and reaches his highest altitude of 54° a little after 4:00AM and then fades into the dawn,

Dwarf Planet Pluto, with his five moons shines at a dim +14.4 in Capricorn, the Sea Goat.

Dwarf Planet 136108 Haumea, her ring and moons Hiʻiaka and Namaka, shines at a faint magnitude of +17.4 in Bootes the Herdsman

Dwarf Planet 136472 Makemake with his moon S/2015 (136472) 1, nicknamed MK1 by the discovery team. faintly shines at magnitude +17.2 in Coma Berenices.

Dwarf Planet 136199 Eris and her moon Dysnomia, originally referred to as Xena and Gabrielle, is barely visible in the most powerful telescopes at magnitude +18.7 in Cetus the Sea Monster.

At least five additional bodies with the preliminary criteria for identifying dwarf planets, and though not “officially” declared as such, are generally called dwarf planets by astronomers as well.

90482 Orcus, and his moon Vanth shines at magnitude +19.1 between Hydra, the Sea Monster and Serpens the Snake.
50000 Quaoar,and his moon Waywot shines at magnitude +18.6 in Ophiucus the Serpent Bearer,

90377 Sedna, the coldest, and at one time, the most distant known place in the Solar System, glows faintly at magnitude +20.9 in Taurus the Bull.

225088 Gonggong, and his moon Xiangli glows dimly at +21.5 magnitude in Aquarius the Water Bearer.

Unnamed Dwarf Planet 2014 UZ224, nicknamed “DeeDee” for “Distant Dwarf” is 8.5 billion miles from the Sun, at magnitude +23.1 in Eridanus the River.

Currently the most distant observable known object in the Solar System, and asteroid unofficially called Asteroid 2018 AG37, and nicknamed FarFarOut, glows at a barely detectable +25.5 magnitude in Lynx.

FarFarOut is 12,246,241,135 miles or in Light Time, 18 hours, 15 minutes and 40.1951 seconds from Earth.

The most distant man-made object, Voyager 1, still operating after 45 years, 9 months and 19 days is 14,830,405,205 miles, or in Light Time, 22 hours, 6 minutes and 52 Seconds from Earth as of 7:46 PM, June 24, sailing through Ophiuchus the Serpent Bearer.

There are 1,298,061 known asteroids as of June24, per NASA.

5445 planets beyond our solar system have now been confirmed as of June 14, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/.

July’s Full Moon occurs July 3 at 6:40 AM CDT or 11:40 UTC, when the Moon will be located on the opposite side of the Earth as the Sun and its face will be fully illuminated.

July’s Full Moon is called “Buck Moon” in Native American folklore. This moon gets its name because the male buck deer begin to grow their new antlers at this time of year. It has also been called “Full Thunder Moon” & “Hay Moon”.

This is also the first of four supermoons for 2023. The Moon will be near its closest approach to the Earth and may look slightly larger and brighter than usual.

During a Full Moon the Moon’s magnitude is -12.7.

The moon will be at Perigee or its closest approach to Earth on July 4, when she will be 223,787 miles from Earth.

Last Quarter Moon, or when the moon has only the Eastern side illuminated, will occur July 9 at 8:47 PM CDT or 1:47 UTC on July 10.

During the Quarter Moon the Moon’s magnitude is -10.0.

New Moon, when the Moon is located on the same side of the Earth as the Sun and will not be visible in the night sky. will occur July 17 at 1:31 AM or 18:33 UTC.

This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

The moon will be at Apogee or its farthest distance from Earth on July 20, when she will be 252,457 miles from Earth.

First Quarter Moon, or when the moon has only the Western side illuminated, will occur July 25 at 5:06 PM CDT or 22:06 UTC.

Though it won’t peak until the night and morning of August 12 & 13, the Perseid Meteor Shower begins July 17, and lasts until August 24. This shower, associated with comet Swift-Tuttle will peak at 60 meteors per hour in August.

The Delta-Aquariad Meteor shower peaks on the night of July 28th into the morning of the 29th.
This shower annually occurs from July 12 through August 23 is made up of debris from Comet Marsden Kracht and produces a ZHR or Zenith Hourly Rate of 20 meteors per hour.

The nearly full moon will block most of the fainter meteors this year. But if you are patient, you may still be able to catch a few good ones.

Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Aquarius, but can appear anywhere in the sky.

This month’s meeting will be on July 11 at 7PM at the National Weather Service Forecast Office at the Shelby County Airport,

Hope to see you there!

Hi Everyone,

I hope this finds you well as we ease into summer!

May has been unusual, to me at least, as it’s the first May I remember where I had to turn a heater on. Of course, it may be because the more ancient I get, the colder I get.

I was originally supposed to be born on a tropical island. Unfortunately, the stork had navigational issues and I ended up in Birmingham instead. Fortunately, it was Birmingham Alabama, rather than Birmingham Michigan.

I am ready for warmth & mosquitoes. Horseflies and fireflies, which we always called “lightning bugs.”

I don’t mind sweating a gallon or two. That’s what water is for.

Here’s wishing you a happy and safe summer!

2023-2024 officers for ALERT!
By
Casey Benefield NZ2O

We have quite a diverse and strong array of skills within ALERT, serving the NWS and amateur radio’s link to the NWS!

• President: Johnnie Knobloch, KJ4OPX Johnnie is active in the amateur radio community, wearing quite a few hats! He’s currently serving as our Alabama ARES Assistant Section Manager, LDS Emergency Coordinator, and Vice President of the Central AL chapter of the National Weather Association.
• Vice President: Casey Benefield, NZ2O Lauren has stepped down as VP, as her activity with SSFD has/will only increase. Casey is back as VP for this term. Primary activities with ALERT will continue to include the background technical side. You can find Casey on LinkedIn most of the time, or via email, callsign at ALERT-Alabama.org.
• Treasurer & Membership: Bill Rodgers, K4FSO Bill continues as treasurer into this term. Bill is also quite active in amateur radio by day, and IT Systems Engineer by night (or the other way around, depending on the week)! He’s one of the guys that set up amateur radio, allowing middle school students talk to astronauts on the International Space Station, among other projects.
• Secretary: Justin Glass, N0ZO Justin continues as secretary into this term. Justin is a VE for Laurel VEC, administering free amateur radio license exams, with Central AL ARC. His mobile amateur radio setups are quite nice, and I’m starting to think of him as a master of remote control and IoT (Internet of Things).
• NWS Liaison: Russell Thomas, KV4S Russell continues as NWS Liaison and Station Trustee. Russell has brought us much greater digital amateur radio integration, such as bridging DMR, Echolink, AllStar, D-Star (XRF), in an effort to make it easier for areas not reachable via VHF/UHF to connect with ALERT and K4NWS (National Weather Service Birmingham). He is instrumental with experimenting with technologies that may aid ALERT in its mission to get ground-truth severe weather reports to NWS, as well as liaising with other regional Skywarn groups, as we work together to cover edge counties.
• Public Information/Training: Casey Benefield, NZ2O Casey likes anything having to do with data and technology.
• Board Members: Dale Chambers, KD4QHZ; Mark Wells, WD4NYL; Casey Benefield, NZ2O; Johnnie Knobloch, KJ4OPX; Russell Thomas, KV4S

Duties for Officers:
• President Appoints the nominating committee of 2 members in March for next election. Presides/conducts all meetings. Votes only in case of tie at regular meetings. Secures meeting space for meetings. Appoints committees for specific tasks, be a member of committees. Appoints non-elected officers: Operations, Public Information, Training.
• Vice President In event that the President is unable to perform duties of office, the VP steps in to perform the duties in absence, and if necessary becomes President and holds office for the remainder of the term.
• Treasurer & Membership Receives all monies, and maintains accurate record of all receipts and expenditures. Reports activities and treasury status at each monthly meeting, including regular/emergency expenditures. Maintains member roster and collects dues, notifies members of dues becoming due.
• Secretary Maintains the official minutes of meetings of ALERT. Maintains copies of bylaws and keeps a record of all changes to the bylaws. In the event of the President and VP becoming unable to fulfill the office of President, the Secretary would hold the office for the remainder of the term or until a special election can be held to fill the vacancy
• NWS Liaison Serve as the official contact person between ALERT and the NWS for issues/changes in radio operations that need to be addressed by ALERT/NWS. Keeps and updates the official callout lists and schedule. Upon NWS request, issues call-outs to the NWS, coordinates the response/shifts. If needed, contact responders and remind them of scheduling. Provides NWS with a ‘callout tree’ of personnel who may initiate callouts, in the even the liaison officer is unavailable
• Operations (Appointed by President) Resolves any communications problems outside the NWS (repeater, link trouble). This officer has charge over ALERT-owned computer and communication equipment, with leeway to modify, repair, augment or enhance ALERT’s capabilities as he sees fit. The Operations and NWS Liaison Officers shall work to keep the training officer informed of any new procedures and equipment, to keep members updated.
• Training (Appointed by President) Maintain and update the procedures manual for operations at the National Weather Service. Provide workshops at the NWS to all Operational Members of ALERT, intended to provide hands-on training in the operations of the K4NWS station Amateur Radio and computer equipment. As new equipment and technology is adopted, the training officer shall provide update briefings or trainings to members to keep them aware of the changes.
• Public Information (Appointed by President) Be a liaison between ALERT and news organizations. Currently, this includes web/social media engagements, as our involvement with the news is somewhat limited. Hamfests and contact with other radio clubs is often a part of the position.
• Board of Directors Appoints or continues the trustee of the K4NWS callsign. The board of directors reviews challenges to membership approval, member standing, discipline, constitutional amendments submitted to the board (to present to membership), hardship review for dues, and conducts any other ALERT business not delegated otherwise in the bylaws. Meetings are held every June, September, December, March, or any time the President calls a special session. *Board meetings, except for executive session, are open to ALERT’s voting membership. The board is composed of President, Immediate Past President, Station Trustee, A two year term at-large member, a one year term at-large member, appointed by Presidents. Terms can be consecutive.

2023 Atlantic Hurricane Season Begins

The Atlantic Hurricane Season officially begins June 1. The National Hurricane Center, to err on the side of caution in case there was an early arriving storm, began issuing outlooks on May 15.

The first subtropical cyclone of 2023 has already occurred, though it wasn’t known at the time of its existence.

The National Hurricane Center in its normal process of re-assessing weather systems has determined that an area of low pressure which formed off the northeastern coast of the United States in mid-January should have been designated as a subtropical storm.

This storm has been designated as AL012023. The next system will be designated as AL022023.

If the system begins as a tropical depression, then it would be given the designation “Tropical Depression Two”, and if it becomes a tropical storm, it will be named Arlene.

NOAA’s Climate Prediction Center is predicting a near-normal Atlantic hurricane season this year. NOAA predicts a likely range of 12 to 17 named storms, of which 5 to 19 could become hurricanes, including 1 to 4 major hurricanes.

NOAA provides these ranges with a 70% confidence. An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

As mentioned last month, both Colorado State University and Accuweather are also predicting “normal” seasons.

NOAA scientists expect El Nino conditions to develop, which tend to suppress Atlantic activity. However, there is the possibility that this could be offset by favorable conditions local to the tropical Atlantic Basin, including the potential for an above-normal west African monsoon, which produces African easterly waves and seeds some of the stronger and longer-lived Atlantic storms, and enhanced sea surface temperatures in the tropical Atlantic Ocean and Caribbean which provides more energy to fuel storm development.

In the grand scheme of things, it doesn’t really matter how many storms form, what matters is where they end up arriving. A year with 28 storms that never reach land isn’t overly significant, where a year with only one named storm and it being a repeat of Katrina, Camille or Andrew is.

With the 2023 North Atlantic Hurricane Season beginning it is a good time to review our preparedness plans.

This has become an annual tradition, this is the only Newsletter rerun that you ever see, and it grows a little longer year by year.

The source for much of this information is the late John Hope of the National Hurricane Center and later The Weather Channel.

While at the NHC, Hope developed a theory called the John Hope Rule. It consists of two parts. Part 1 states: “If a system is not a bona fide tropical storm before crossing the Windward Islands, or the Lesser Antilles, it will not survive the trek across the Eastern Caribbean Sea. If the wave is still present, formation in the Western Caribbean is possible.” Part 2 states: “If the structure of a wave or storm is good, never discount it or write it off”.

I call that “The Oops Rule” for when something shouldn’t have developed, but it does it anyway.

……………………………………………………………………………………………………………………….

Hurricane Impact & Hurricane Response

Alabama is impacted by hurricanes in three ways:

1. Direct Impact – Where the core of the storm or the rain / wind field strikes or passes through a portion of Alabama. Examples being Hurricane’s Fredrick, Opal, Ivan, and Katrina.

2. Indirect Impact – where the core is not over Alabama, but the feeder bands are passing through and causing havoc. Rita’s feeder bands being a good example, which dropped 21
tornadoes over west Alabama in a 4-hour period.
3. Distant Impact – A storm that is not even near Alabama but affecting our weather. Such as with Olivia, a Pacific Hurricane which was off Western Mexico. Her moisture was captured by the jet stream, crossed the Sonora desert, the Arklatex region & dumped monsoon type rains on Alabama & Mississippi, causing flooding.

ALERT typically will activate during scenarios 1 & 2. ALERT’s coverage would concentrate on monitoring D-Star directly and using a liaison station to monitor HF offsite on 3.965 MHz or the backup 40-meter frequency of 7.243 MHz

Then as the storm moves northward into the BMX County Warning Area the focus would then shift to the individual county Skywarn Nets, as we would do during a “normal” callout.

HF Gulf Coast Nets to monitor are:

Primary State ARES Frequencies & Nets for Gulf of Mexico & regular meeting times.

3.965 MHz Alabama Emergency Net Mike 4:00 PM Sunday*
3.940 MHz Florida Amateur Single Sideband Net 6:00 PM
3.975 MHz Georgia Single Sideband Net 7:30 PM
3.910 MHz Louisiana Traffic Net 6:30 PM
3.862 MHz Mississippi Section Phone Net 6:00 PM
3.873 MHz Texas Traffic Net 6:30 PM

* Note that this is also the frequency of the Alabama Traffic Net Mike, meeting daily at 5:30PM Central Time & Sunday’s at 8:00 AM Central Time and the Alabama Day Net, which meets daily at 10:00 AM Central Time.

Wide Coverage Nets

14.235 MHz Hurricane Watch Net As Needed
3.935 MHz Central Gulf Coast Hurricane Net 1:00 UTC

The Hurricane Watch Net is only activated when a storm is within 300 miles of a populated land mass. Normally you shouldn’t check into this net, but only listen. Only check in if you have a legitimate need to do so. A legitimate need being emergency or priority traffic or if the NCS specifically calls for a station in Central Alabama, only then should you pick the microphone up. Occasionally, if there is a lull in activity, they may give a call for general check-ins. But don’t be surprised if they don’t. Helping stations in the affected area is their primary concern.

Once upon a time a, which if I remember correctly was in 1988 when Gilbert, was rearranging Jamaica, the NCS asked “do we have any stations in the affected area, the affected area only?” Some fellow from Zero-land, piped in and very slowly drawled out “This is Kay Zero Que Arr Emmm, Homer over in Tulsa Oklahoma, just wanting to tell you fellers what a fine job, a fine job you fellers are doing. And, if I can be of any help, any help at all just let me know. This is Homer, K0QRM, over in Tulsa Oklahoma on frequency and standing by on the side.”

What harm was done? You might ask.

First, it hampers any emergency traffic trying to reach the net.

Fifteen distress calls probably could have been received and handled in the time it took Homer to ooze over “on the side”.

Secondly, it exacerbates the problem of NCS operator fatigue. Sometimes the adrenalin rush of the moment can keep an NCS sharp and “in the game” as it did with Ivan when I was on the air at K4NWS for 16 hours straight, but, minus that adrenalin rush, when it’s just station after station, checking in hour after hour, just so they can say they checked in, it can wear an NCS out.

So, learn from a bad example. Don’t do this.

For the most reliable storm information, the National Hurricane Service and the local National Weather Service Forecast Offices for your area and the areas affected should always be your prime source.

The local offices know the historical conditions, topographical factors and the local quirks which make up the microclimate of the area, which may influence or alter situations on a local level, which a forecaster 500 miles away, no matter how good they may be, might not have a clue about.

Major media sources can be trusted, however, internet sources, especially social media prophets and gurus should never be substituted for official sources.

Social media reports and websites, until one knows their sources, the timeliness of their information, their track record of veracity and in some cases their motives, should, for one’s own safety, be viewed with a jaundiced eye and treated with the same caution as you should with all internet sources. Don’t just believe everything you read. Even if you agree with it or want it to be true. And, that applies to a very wide spectrum of subjects, as you cruise down the Disinformation Superhighway.

Don’t spread information without it being verified from authentic sources, no matter how flashy or how convincingly it may be presented. Your credibility and very possibly the safety of others is at stake.

That includes my wise weather prognostications also.

Just remember that some who would have you believe their “expert opinions” are also the same ones who would have you believe that King Charles is a shape shifting lizard dude. And, though I have always suspected that my second-grade teacher, “Mrs. Martin” aka “Madre De Satanás”, might have actually been one, in the case of the King, it is still yet unproven.

Hurricane Tracking Gleams And Glints From Mark’s Crystal Ball

I’ve always enjoyed trying to second-guess the National Hurricane Center. It’s fun! Many times our forecasts agree, they have outguessed me an honorable number of times & every now and then, when Divine Providence intervenes, I have beaten them.

The following are some random hints and items I have stored in my dusty brain, which every now and then come into play as I gaze into my tropical crystal ball.

The first thing I will touch on is the name itself – “Hurricane” and its origin.

Some believe the name originated from “huracan” which was the Carib peoples of Northern South America term for “evil wind”. Others credit the Mayans of Central America and believe that is originates from “Hurakan”, the Mayan god of wind, storm and fire. According to the Mayan Creation Myth, Hurakan caused the Great Flood after the first humans angered the gods. According to the myth, he lived in the windy mists above the floodwaters and repeatedly called forth the earth until land came up from beneath the seas.

Whichever its origin, it is known that the names Hurican and Hurikan predate the appearance of Europeans on the horizons of what would become known as the “Americas”, stretching back into the dim mists of antiquity.

The Spanish word for “Hurricane” is “Huracan” to this day.

A couple of terms which you have undoubtedly heard of is “El Niño” & “La Niña”.

El Niño or more precisely the “El Niño Southern Oscillation” (ENSO), is a planetary-scale climate variation caused by interactions between the atmosphere and the Central and Eastern Pacific Ocean, which in turn affects the tropical climatology of the Gulf of Mexico and the North Atlantic Ocean.

El Niño refers to unusually warm ocean temperatures that occur every 2–7 years around Christmas time along Peruvian coast, extending into equatorial eastern and central Pacific Ocean, while La Niña refers to unusual cooler temperatures. A normal temperature is referred to as “neutral”.

Though many factors are used in making seasonal hurricane forecasts, El Niño & La Niña weigh heavily in the process.

The warm El Niño favors stronger hurricane activity in the central and eastern Pacific basins due to lower vertical wind shear, weaker trade winds and greater instability, while suppressing it in the Atlantic basin due to stronger wind shear tearing and shredding the thunderstorm columns of storms trying to form, stronger trade winds hampering large scale organization and greater atmospheric stability.

The cool La Niña does the opposite suppressing hurricane activity in the central and eastern Pacific basins and enhancing activity in the Atlantic basin.

2021 is La Niña year, which is one of the reasons why 2021 is expected that we will have a vigorous tropical season.

Some other hurricane facts are:

The maximum number of tropical systems that the Atlantic Basin (which includes the Gulf and Caribbean) can simultaneously contain, and support is five storms.

If major tropical systems get too close to one another they don’t merge as thunderstorms often do. The upper-level winds associated with each storm counteract or buffets each other preventing this from occurring.

If you have a large storm and a smaller storm enters the influence or wind field of the larger storm, the smaller storm will tend to rotate counterclockwise around the primary storm in a process called the Fujiwhara Effect.

If the smaller storm is very weak, say a tropical storm versus a Category 4 storm, it is possible that the smaller storms circulation can be totally disrupted by the larger storm and then it can be absorbed into the larger storm’s circulation. See http://www.youtube.com/watch?v=fNjUSsqJgek&feature=relmfu as Typhoon Ma-On gobbles up Tropical Storm Tokage in 2011.

Tropical systems, for all of their tremendous energy, are totally without an engine or steering mechanism, but are at the mercy of the whims of the upper-level winds. A tropical system can spin all it wants to, but unless the storms thunderstorm columns reach high enough to snag the upper-level winds, and then act as a sail, the storm is going nowhere fast. If the upper-level winds die down, the storm can drift aimlessly for days.

If the storm sits still long enough, it will begin to dissipate due to it stirring up the deeper cooler waters beneath it and it cooling the sea surface temperature below the 80 degree critical threshold needed to sustain a tropical storm. This is “upwelling”. The one exception to this rule is if it is sitting over the Gulf Stream, as the incoming current will continually replenish the warm water beneath the storm.

Air pollution or the lack thereof can influence tropical activity. NOAA has found that a 50% decrease in pollution particles and droplets in Europe and the U.S. is linked to a 33% increase in Atlantic storm formation in the past couple decades, while the opposite is happening in the Pacific with more pollution and fewer typhoons. Less pollution lets more sunlight to reach the ocean surface and vice versa.

Saharan sand blown across the Atlantic and into the Gulf will limit tropical development by blocking sunlight. This is a common occurrence which happens every spring and summer.

A well-formed storm will have a perfectly circular Central Dense Overcast or CDO, an area of thunderstorms surrounding the eye wall, with “feeder bands” of thunderstorms spiraling inward counterclockwise, parallel to the storm’s inbound horizontal winds, and “feeding” energy from the warm tropical ocean into the storm.

The winds being drawn into the eye, once arriving can only go in one direction – up – and in a well formed storm the system will be capped by high pressure, which helps evacuate these winds as they reach the stratosphere. This forms a false cirrus shield of clouds rotating in a clockwise fashion, as the winds are vented outward. If the storm has a tear drop shape or a long plume of clouds extending from the storm, this indicates heavy shearing, which will limit its growth, or shred the circulation. The storm will be veered by the shearing and try to deflect towards the direction of the plume.

A poorly organized storm can have a completely exposed center, with the cloud shield nowhere near the center. Until it starts “stacking up” it will remain a weak storm.

Intense, Category 3 or greater hurricanes will go through a process called an “eyewall replacement cycle”. In this case the eyewall contracts so small that some of the outer rain bands may strengthen and form an outer eyewall, causing the storm to weaken by robbing energy from the inner eyewall and will eventually choke it out completely and replace it, causing the storm to re-intensify.

This is a common occurrence. Less common is when you have a triple eyewall, as was the case with Typhoon June and Hurricane Juliette.

The fastest intensification from a Tropical Storm to a Category 5 Hurricane occurred with Hurricane Wilma in 2006, which in 24 hours went from 70 mph to 155 mph and then vacationed in the Yucatan.

The fastest intensification from a Tropical Depression to a Category 5 Hurricane occurred with Wilma & Hurricane Felix, which took just 54 hours to bloom and then blessed Nicaragua with its presence in 2007.

Honorable mention also goes to Hurricane Delta, which took just took just 36 hours to grow from a Tropical Depression to a Category 4 storm in October 2020.

The World Champion is Super Typhoon Hagibus which grew from a tropical storm to the equivalent of a Category 5 storm in only 18 hours in 2019.

Tropical systems cannot penetrate frontal boundaries. If a tropical system is threatening the coast, and you see that a front will be approaching the coast from the West, don’t worry about the coast, as it will either stall the storm, deflect it to the Northeast or as in the case of 2009’s Tropical Storm Danny, it can absorb a weak storm.

When looking at hurricane forecast model ensembles, such as http://derecho.math.uwm.edu/models/ & http://www.ral.ucar.edu/hurricanes/realtime/current/,
you can judge the “confidence” of the models by the grouping of the plotted tracks. If the plots are tightly grouped together, you can have “high confidence” in the reliability of the track and if the timing given by the plots agree, that also. The narrower the spread, the greater the confidence, and the wider the spread, the lesser the confidence. Some tracks will be obviously wrong, those you can dismiss. If the forecast tracks go look like they were written by a drunken spider, with paths going in every direction at once, that storm is heading nowhere fast.

One must be very cautious of jumping to conclusions when they see a forecast model indicating a tropical system and then blasting on the internet that “it’s about to get real in Mobile” and then causing people to panic and spread even more rumors online, when in fact that one model shows nothing 12 hours later. A single model can be misleading or just plain wrong. Consistency is the key. If a model consistently and persistently shows a system, then you know that THAT model thinks something will happen. But what do the other models say? Do they agree with the intensity and forecast track? Do they even show anything at all? That’s why the NHC is the best place to get your information.

The NHC issues outlooks for 2 days and 5 days. Beyond that everything is guesswork.

If a storm exists, they will issue full advisories every 12 hours and intermediate advisories every 6 hours.

One staple of NHC graphics is the “forecast cone” or “cone of uncertainty”, which represents the probable track of the center of the tropical cyclone.

The size of the cone is drawn so that about two-thirds of the time, the center of the storm will remain in the cone.

The cone does not take the size or shape of the storm into account, only where they think the center will be located. Some storms are large with damaging winds extending far beyond the cone. Some storms are compact, and the damaging winds lie within a small area in the cone. Some storms are lopsided, with nothing much happening on the western side leading people to carp about “over hyped forecasts for ratings” while the same distance away on the eastern side of the storm people are literally hanging on for dear life.

It is always to be remembered that a hurricane is not a point on a map; impacts often occur well outside of the core.

The cone indicates the forecast up to five days out from the last recorded position of the storm, with each increase in time from this initial period, the error factor grows.

Forecast Period (hours) Average NHC Forecast Track Error (miles)
12 9.1
24 26.3
36 42.0
48 56.9
72 73.8
96 109.7
120 221.7

This is why one should always get the latest information from the NHC, as they are constantly fine tuning their forecasts.

Tropical storms and hurricanes are steered by winds aloft, and the overall track can be a function of a storm’s intensity. These days, intensity forecasts still have some limitations, but there is a concerted effort to make improvements.

Theoretically Tropical Storms will lose strength over land. The 1997 version of Danny (which came up I-65 reached Birmingham and then turned East heading along I-20 towards Atlanta, as if He knew what he was doing) forgot this and strengthened while over the swamps of South Carolina and then moved into the Atlantic as a rejuvenated system heading for New England. The theory at that time was that the swamps were so warm and humid that the storm “thought” it was over the sea. Now they say it was due to the effects a frontal system closely following the storm. I always preferred the first explanation, as it seemed more logical, if not niftier.

Storms named “Danny” and I are old companions, incidentally. In 1985 I accidentally managed to intercept Hurricane Danny a few hours after it struck Louisiana. I remember the feeder bands passing with heavy rain and gusts, and then it calming and clearing in between waves. “Looks like it can’t decide whether it’s coming or going” said the old guy at a truck stop where I was refueling. I also remember making a ham sandwich for an old dog at a rest stop. Old Shep looked hungry, so I fixed him one. He woofed it down, thanked me kindly and then disappeared into the mist.

If a storm strikes just West of Alabama, expect sorry weather. If it strikes just East of Alabama, expect dry weather and lowering humidity, as the storm drags the moisture away with it.

If a 120 MPH storm is moving North at 20 MPH the wind field around the eye will be affected as follows. The winds on the Eastern side combine and are in effect 140 MPH, while the winds to the West subtract and are in effect 100 MPH. This is the “fast moving hurricane rule”.

If the Eastern Pacific Basin is active, the Atlantic Basin will be quiet & if the Atlantic Basin is active the Eastern Pacific Basin will be quiet.

Category 5 storms have never occurred in both the Atlantic & Pacific Basins in the same year.

Hurricanes can cross Central America from either the Atlantic or Pacific Basins, enter the other Basin and restrengthen and be renamed. The last being in 1996 when Category 1 Hurricane Cesar which scraped Northern South America, crossed Central America & restrengthened into Category 4 Hurricane Douglas.

Then there is the case of 1961’s Hurricane Hattie, which formed in the Caribbean, stuck Central America on Halloween, dissipated, then after reaching the Pacific, her remnants helped generate Tropical Storm Simone on November 1. Simone then turned Northwest striking Southern Mexico on November 2, dissipated and her remnants crossed Mexico, entering the Gulf of Mexico. These remnants in turn helped generate Tropical Storm Inga, which dissipated on November 8.

Alphabetical name position can’t be used as an indicator of possible storm strength. Andrew and Opal, both unruly guests, with names toward the opposite ends of the alphabet, are good examples.

Never underestimate the potential impacts of late season storms. Category 5 Hurricane Mitch was active from October 22 – November 5, 1998, with maximum sustained winds of 180 MPH. This storm struck Central America, Yucatán Peninsula & South Florida causing 6.2 billion dollars in damage and caused 11,000 deaths.

Remember that winds do not blow OUT of a hurricane; they are drawn INTO the storm in a spiraling motion. By factoring in the Coriolis Effect of the Earth’s rotation and the counter-effects of surface friction you can determine the general direction of any tropical storm or non-tropical low-pressure center using the surface wind direction as follows:

Wind Direction Storm Center Location

South North West
Southeast West
East Southwest
Northeast South
North Southeast
Northwest East
West Northeast
Southwest North

Calm winds suddenly occurring during a hurricane indicates the eye is over you. The winds will return just as suddenly, often stronger in the opposite direction.

My sister’s family was living at Clark Air Force Base in the Philippines in 1974, when Typhoon Bidang passed directly over. When the winds suddenly died down, they knew they were in the eye. Suddenly there was a knock on the door and opening it she found a delivery van with the furniture she had ordered. The Filipinos crew unloaded everything, said “thank you” and drove off into the darkness as the rear of the eyewall appeared and began blowing at full force.

NHC Hurricane Tracking Chart PDF’s

Here are handy hurricane tracking charts from the National Hurricane Center.

For the Atlantic Ocean: http://www.nhc.noaa.gov/pdf/tracking_chart_atlantic.pdf
For the Pacific Ocean: http://www.nhc.noaa.gov/pdf/tracking_chart_epacific.pdf

Someone once asked me “why do you bother tracking the Pacific ones?” For practice, so that when the Atlantic ones do appear you are already ahead of the game experience wise.

Mark’s Almanac

Originally the fourth Roman Month, June at one time had 29 days, until Julius Caesar in a glow of inspiration added the 30th day.

What June was named for is uncertain. Some say it was named for Juno, wife & sister of Jupiter. Juno was the goddess of marriage and a married couple’s household, so some consider it good luck to be married in this month, which is why June has become a month for so many marriages.

The beginning of meteorological Summer is June 1.

Storm activity retains many of the characteristics of spring, but more and more the pattern takes on the summer pattern of pop-up thunderstorms.

Hurricane season begins, June 1, however June hurricanes are usually small and of minor intensity, occurring roughly once every two years.

The centers for June Tropical Cyclone activity are the extreme Western Caribbean, with the storm tracks striking the Yucatan or veering toward Western Florida & the Southwestern Gulf of Mexico, with other storm tracks aiming toward the Mexican mainland.

From 1851 to 2022 there have been 99 Tropical Storms and 33 Hurricanes, of which 19 impacted the United States. The most notable June hurricane was Audrey, one of the deadliest tropical cyclones in US history, which killed 416 as it devastated the southwestern Louisiana coast in 1957.

The center of maximum tornadic activity shifts northward over Kansas and Iowa. Activity in Texas and Oklahoma dies down. There is a 5% decrease in tornadic activity over the May average & by June 4th 50% of the year’s tornadoes have occurred.

Days continue to grow longer as the Sun’s angle above the noonday horizon increases from 78.5 degrees at the beginning of the month to maximum of 79.9 on Summer Solstice on June 21 and then lowering to 79.6 degrees at the month’s end. Daylight increases from 14 hours 14 minutes on June 1 to the maximum daylight of 14 hours 23 minutes at Summer Solstice on June 21 and then decreases to 14 hours 21 minutes on June 30.

 

Sunrise and sunset times for Birmingham are:

June 1 Sunrise 5:38 AM Sunset 7:52 PM
June 15 Sunrise 5:37 AM Sunset 7:59 PM
June 30 Sunrise 5:40 AM Sunset 8:01 PM

Looking skyward, the Sun, magnitude -26.7 is in Taurus.

Mercury, magnitude +0.5 in Aries the Ram, is hidden deep in the glow of sunrise.

Venus, magnitude -4.4 in Gemini the Twins, is near her highest altitude above the western horizon, which she will reach on June 4.

She becomes visible just after 8;00 PM, 34° above the western horizon, as dusk fades to darkness. She will then sink towards the horizon, setting a little after 11 PM.

In a telescope Venus is a dazzling half-Moon shape, about 50% sunlit. She gets larger each day while waning in phase. It will become a bigger, thinning crescent dropping lower from mid-June through mid-July.

Earth, magnitude -4.0, as viewed from the Sun, is in the constellation Sagittarius The Archer.

Mars, magnitude +0.6 in Cancer the Crab, is an early evening object, becoming visible around 8:30 PM, 36° above the western horizon, as dusk fades to darkness. He will then sink towards the horizon, setting just before midnight.

Dwarf Planet Ceres, magnitude +8.1, is in Virgo the Virgin.

Jupiter, magnitude –2.4, in Aries the Ram, recently passed behind the Sun at solar conjunction and is now visible in the predawn sky rising two hours before the Sun, around 3:30 AM, reaching an altitude of 19° above the eastern horizon before fading from view as dawn breaks.

Saturn, magnitude +0.9, in Aquarius the Water Bearer, is emerging from behind the Sun, and is visible in the morning sky, rising just after 1 AM and reaching an altitude of 39° above the south-eastern horizon before fading from view as dawn breaks.

Uranus, 5.9 in Aries the Ram, is lost in the glare of the Sun,

Neptune, 7.8 magnitude in Pisces the Fish, rises 3 hours and 39 minutes before the Sun, reaching an altitude of 28° above the south-eastern horizon before fading from view as dawn breaks.

Dwarf Planet Pluto, with his five moons shines at a dim +14.4 in Capricorn, the Sea Goat.

Dwarf Planet 136108 Haumea, her ring and moons Hiʻiaka and Namaka, shines at a faint magnitude of +17.3 in Bootes the Herdsman

Dwarf Planet 136472 Makemake with his moon S/2015 (136472) 1, nicknamed MK1 by the discovery team. faintly shines at magnitude +17.2 in Coma Berenices.

Dwarf Planet 136199 Eris and her moon Dysnomia is barely visible in the most powerful telescopes at magnitude +18.7 in Cetus the Sea Monster.

Discovered January 5, 2005, Eris was initially labeled by NASA as the “Tenth Planet” and was temporarily named “Xena” after TV’s “Xena The Warrior Princess” and her moon “Gabrielle”, after Xena’s sidekick.

But, since planets and dwarf planets are named for mythological characters and not TV characters, this world was officially dubbed “Eris” the Greek goddess of strife and discord.
The name was proposed by the Caltech team on September 6, 2006, and it was assigned on September 13, 2006.

I preferred “Xena”, but they forgot to ask for my valuable input.

They need one named “Buffy” for “Buffy The Vampire Slayer” also. For back in the day The Slayer rocked.

At least five additional bodies with the preliminary criteria for identifying dwarf planets, and though not “officially” declared as such, are generally called dwarf planets by astronomers as well.

90482 Orcus, and his moon Vanth shines at magnitude +19.1 between Hydra, the Sea Monster and Serpens the Snake.

50000 Quaoar,and his moon Waywot shines at magnitude +18.6 in Ophiucus the Serpent Bearer,

90377 Sedna, the coldest, and at one time, the most distant known place in the Solar System, glows faintly at magnitude +20.8 in Taurus the Bull.

225088 Gonggong, and his moon Xiangli glows dimly at +21.5 magnitude in Aquarius the Water Bearer.

Unnamed Dwarf Planet 2014 UZ224, nicknamed “DeeDee” for “Distant Dwarf” is 8.5 billion miles from the Sun, at magnitude +23.1 in Eridanus the River.

Currently the most distant observable known object in the Solar System, and asteroid unofficially called Asteroid 2018 AG37, and nicknamed FarFarOut, glows at a barely detectable +25.5 magnitude in Lynx.

FarFarOut is 12,246,241,135 miles or in Light Time, 18 hours, 15 minutes and 40.1951 seconds from Earth.

The most distant man-made object, Voyager 1, still operating after 45 years, 8 months and 24 days is 14,805,058,006 miles, or in Light Time, 22 hours, 4 minutes and 36 Seconds from Earth as of 6:38 PM, May 29, sailing through Ophiuchus the Serpent Bearer.

There are 1,284,260 known asteroids as of May 29, per NASA.

5419 planets beyond our solar system have now been confirmed as of May 16, per NASA’s Exoplanet Archive http://exoplanetarchive.ipac.caltech.edu/.

June’s Full Moon is “Strawberry Moon” in Native American folklore. This will occur on June 3 at 10:43 CDT or 03:43 UTC on June 4. The Moon will be located on the opposite side of the Earth as the Sun and its face will be fully illuminated. It is called “Strawberry Moon” for it signals the time to start harvesting strawberries, as it is peak strawberry ripening time. Other names are “Rose Moon” and “Honey Moon”.

During a Full Moon the Moon’s magnitude is -12.7.

The Moon will be at Perigee, or her closest point from the Earth on June 6 at 226,713 Miles.

Last Quarter Moon, or when the moon has only the Eastern side illuminated, will occur June 20 at 2:41 PM CDT or 7:41 UTC on June 10.

New Moon will occur June 17 at 11:38 PM CDT or 04:38 UTC on June 18. The Moon will located on the same side of the Earth as the Sun and will not be visible in the night sky. This is the best time of the month to observe faint objects such as galaxies and star clusters because there is no moonlight to interfere.

Summer Solstice will occur at 9:51 AM CDT or 14:51 UTC on June 21. The North Pole of the earth will be tilted toward the Sun, which will have reached its northernmost position in the sky and will be directly over the Tropic of Cancer at 23.44 degrees north latitude. This is the first day of summer in the Northern Hemisphere and the first day of winter in the Southern Hemisphere.

The Moon will be at Apogee, or her farthest point from the Earth on June 22 at 251,865 Miles.

First Quarter Moon, or when the moon has only the Western side illuminated, will occur June 26 at 2:50 AM or 7:50 UTC.

During the Quarter Moons the Moon’s magnitude is -10.0.

The June Bootids Meteor Shower will occur from June 26th until July 2nd. It peaks on June 27th. Normally the shower is very weak, with a Zenith Hourly Rate or ZHR of 1 or 2, but occasional outbursts produce a hundred or more meteors per hour. The source of the June Bootids is Comet 7P/Pons-Winnecke, which orbits the Sun once every 6.37 years.

The First Quarter moon will block out some of the faintest meteors with this unpredictable shower, but if you are patient, you should be able to catch quite a few good ones. Best viewing will be from a dark location after midnight.

Around 10 PM in mid-June, Libra the Scales will be passing due South. When Alpha Librae, the lower-right of the two brightest stars of Libra, is due south, if you look directly below it you will see nothing but horizon. But, if you were at a lower latitude, say 29°, the latitude of Orlando, or points south would see our brilliant, -0.27 magnitude neighbor Alpha Centauri above the horizon.

At 4.37 light years distance, the Alpha Centauri system is nearest star system to our own.

It is a triple star consisting of Alpha Centauri A, also called Rigil Kentaurus, Alpha Centauri B or Toliman and the closest star to the Sun, Alpha Centauri C also called Proxima Centauri, 4.24 light years from Earth,

Alpha Centauri A is a near twin of our Sun in almost every way, including age, while Alpha Centauri B is somewhat smaller and dimmer but still quite like the Sun. The third member, Proxima Centauri is a much smaller red dwarf star that travels around the A-B pair.

Proxima Centauri has three known planets: Proxima b, an Earth-sized exoplanet in the habitable zone or so called “Goldilocks Zone” – not too hot and not too cold to support some form of life if it has a suitable atmosphere. Proxima c, a super-Earth, which is possibly surrounded by a huge ring system and Proxima d, which orbits very closely to the star.

Alpha Centauri A may have a Neptune-sized habitable-zone planet, though it is not yet known to be planetary in nature and could be an artifact of the discovery mechanism. Alpha Centauri B has no known planets.
