Monthly Highlights
We are sad to report on the passing of Albert H. Nagler on October 27. He will be missed, but his legacy lives on via the stunning views through his amazing eyepieces. More about his legacy here: https://skyandtelescope.org/astronomy-news/al-nagler-1935-2025/
The JWST has made the first detection of complex organic molecules (COMs) around a star in another galaxy. The MIRI instrument detected acetaldehyde, acetic acid, ethanol, methanol, methyl formate, and 14 other COMs around the massive protostar ST6 in the Large Magellanic Cloud. https://iopscience.iop.org/article/10.3847/2041-8213/ae0ccd
A possible major shift in cosmology is brewing. Recent measurements by the Dark Energy Spectroscopic Instrument reveal a possible major shift in cosmology. A standard distance candle, the Type 1a supernova, may not be so standard and may depend on the age or their progenitor stars. More observations by the now operational Vera C. Rubin Observatory will allow for more definitive tests. https://academic.oup.com/mnras/article/544/1/975/8281988?login=false
Get ready for the LEONIDS!!! Currently active and peaking on the night of November 16-17, a 9% crescent moon will not interfere.
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
TAURIDS
Both Southern (September 20 - November20) and Northern (October 20 - December 10) versions of this shower overlap and will be responsible for many fireball reports despite the full moon on November 5. Don't let the low ZHR of 5 for them both dissuade you - will you hear a sizzler originating from 2P/Encke?
LEONIDS
Active November 6 to November 30, Peaking November 16-17. From 55P/Tempel-Tuttle with a ZHR of 15. Moon only 9% should not interfere!
Open the link: News and Information about Meteor Showers
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......
The 41st annual Winter Star Party was a great success! Many sleep-deprived but happy astronomers report: BEST PARTY EVER!
Don't take my word for it, read the first hand accounts over on Cloudy Nights: https://www.cloudynights.com/topic/941985-winter-star-party-2025/page-3

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 Barb if you wish to link up with Dan. barbyager@aol.com.
SOLAR VIEWING
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 barbyager@aol.com 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: 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.
