May 2024
Compiled by John Panek
This month we shift our attention back to the night sky with a potentially great Eta Aquariid meteor shower – the moon is favorable (New on May 7) and the Earth will pass close to a debris stream left by the parent Halley’s Comet around 3000 years ago. The radiant lies near Zeta (ζ) Aquarii and rises at 2:30 a.m. local daylight time in the continental U.S., reaching an altitude of 20° two hours later. Peak zenithal hourly rate is 50 meteors per hour but since the radiant is not overhead, observed rates are normally a dozen per hour, but rates May 3 may be higher due to our passage through the debris stream.
SCAS CELEBRATES
HONOR THE NIGHT
Ancient cultures measured time by the Moon's phases, the days of each cycle counted out. They knew when the Moon would wax and wane. Who today is aware whether the Moon is crescent, full or gibbous? We no longer honor the night sky. On a retreat with preteen students, far enough from city lights to see the cosmos, on a night when bright Venus cast a shadow, we asked them to turn off their flashlights, let their eyes adjust, Trust their steps in starlight. We honored the night sky.

METEOR SHOWERS THIS MONTH
eta Aquariids
April 15th to May 27th, 2024The Eta Aquariids are a strong shower when viewed from the southern tropics. From
the equator northward, they usually only produce medium rates of 10-30 per hour just
before dawn. Activity is good for a week centered the night of maximum activity. These
are swift meteors that produce a high percentage of persistent trains, but few fireballs.
There are predictions that this shower will be quite strong in 2024 due to interactions of
the particles with the planet Jupiter. Luckily, there will be little interference from the
waning crescent moon in 2024.
Shower details - Radiant: 22:30 -1° - ZHR: 50 - Velocity: 40.7 miles/sec (swift -
65.5km/sec) - Parent Object: 1P/Halley
Next Peak - The eta Aquariids will next peak on the May 4-5, 2024 night. On this night,
the moon will be 14% full.

Here are some tips on how to maximize your time looking for meteors and fireballs during any meteor shower:
- Get out of the city to a place where the city and artificial lights do not impede your viewing
- If you are out viewing the shower during its peak, you will not need any special equipment. You should be able to see the shower with your naked eyes.
- Carry a blanket or a comfortable chair with you - viewing meteors, just like any other kind of stargazing is a waiting game, and you need to be comfortable. Plus, you may not want to leave until you can't see the majestic celestial fireworks anymore.
In case you missed it......
October 2022 Sky & Telescope p. 62 features photos of our two famous SCAS astronomers. The late Don Parker, M.D., renowned Mars astrophotographer, and the late Tippy D'Auria, founder of our annual Winter Star Party were in a group of professional astronomers, editors, and photographers who drove to the Florida Keys in June 2001 to hopefully capture Martian flares of light. All were members of the Assoc. of Lunar & Planetary Observers. The intriguing article begins on P. 59.
BRIGHT COMETS THIS MONTH
Comet 12P Pons-Brooks
Visible just after sunset in Taurus at magnitude 4.6
13P/Olbers
Will reach perihelion in late June. Begins the month in Taurus at magnitude 8.4, brightening rapidly this month moving up into Auriga

We operate by starlight !
SCAS HAM RADIO
Recently, member Dan Zuckerman replaced and upgraded his ham equipment. He was chatting with folks in Europe.
Do we have some retired, or new SCAS ham operators who would like to establish a SCAS radio dept?
It could become very convenient, or necessary in certain future conditions. Consider the astronomy information shared and maybe international SCAS members!
Contact me (Barb) if you wish to link up with Dan. barbyager@aol.com.
SOLAR VIEWING
TOTAL SOLAR ECLIPSE 04/08
Weather permitting SCAS needs solar telescopes at the "front door" to ZooMiami 12400 SW 152nd st, starting this month
There will be large crowds of families. Please CONTACT ME ASAP if you can bring equipment, We are restoring our popular solarviewing events at ZooMiami.
Plans need to be made in advance. Updates will be sent out to members soon.
Interested to join our new solar team? Contact me: barbyager@aol.com . If you have solar equipment or want to help, please send an email to Dr. Lester Shalloway with
your information: drlester3@aol.com.
IN THE SKY
May is a great month for Spring galaxies - check out the Needle (NGC 4565) in Coma Berenices and the
Sombrero (M104) in Virgo. Early May affords an opportunity to see the crescent Moon near Mars, Saturn, and
Mercury just before Sunrise. Greatest elongation of Mercury is May 9, at 26 degrees.
