Our name is the South West Astronomy Observers Group.  We are a group of astronomical observers and Ham Radio operators in the Chicago Metropolitan Area who like to go observing and share our hobby via Amateur Radio.  We meet on the DuPage  (DARC)  Repeater - 145.430 MHz. (TX offset -600KHz. / 107.2 Hz. PL) every Thursday evening at 8:30 PM  to discuss our wonderful hobby of astronomy, and plan observing sessions.
 
The Astronomy Net was founded in February 2001 by Mark - KB9WLX, and is open to all licensed Amateur Radio Operators (Hams).   3rd party traffic is permitted, providing it's done as per FCC rules.   If you have children in the shack, we'd love to hear from them as well!   All Ham Radio Operators are welcome to check in and participate in the net, you DO NOT have to be an astronomer to participate.   Just check in, listen, and learn if you'd like!   Astronomical data reports and other interesting astronomy-related reports are given each week by the Net Control Operator.   Hams that have checked in can exchange any information they may have about astronomy related activities & events, and share any observing experiences that they have had.   Articles, reports, and astronomy discussion sessions are usually provided.   We frequently have some of our listeners check in with live, up-to-the-minute, observing reports during the Net!    Listening to the net on a scanner?   Scroll down to see how you can check in via e-mail!    Interesting astronomy-related web sites can also be shared with the group.   Astronomy-related Product Reviews are also encouraged to help our fellow astronomers make informed purchases!

 
On the next edition of the Astronomy Net:
 
*Learn about astronomy and get help with your equipment and observing skills.  The group will try to answer most of your questions!
*Participate in 'live'  ISS and Iridium Flare Observations!  (when available)
*Listen for interesting & informative astronomy-related Reports and Segments.
*Reports or segments on astronomy are welcomed and encouraged from any members of our listening audience.  Please feel free to share your information with the group on the Weekly Astronomy Net!
* Listen and see if you can answer the "Astronomy Trivia Questions of the Week" (when available)

The Zodiacal Light is caused by sunlight reflected off meteoric dust in the plane of the solar system. Choose a clear, moonless night, about 1-2 hours after sunset, and look for a large triangular-shaped glow extending up from the horizon (along the ecliptic). The best months to view the Zodiacal Light is when the ecliptic is almost vertical at the horizon: March and April (evening) and October-November (morning); times reversed for the southern hemisphere.

* Moonlight will wash out fainter meteors in these showers.

Bold Shower Names indicate the best predicted showers! 

The meteor showers listed above are the easiest to observe and provide the most activity. Particular attention should be noted to the time and moonlight conditions. All these showers are best seen after midnight. Some are not even visible until after midnight. Showers that peak with the moon's age between 10 and 20 days will be affected by moonlight and difficult to observe this year. While the time each shower is best seen remains much the same year after year, the moonlight conditions change considerably from one year to the next. 

Please use the form found HERE from the American Meteor Society to report any Meteors that you see.    Instructions on how to complete the form can be found HERE.

Upcoming Public Observing Sessions:
Public Observing Sessions or 'Public Star Parties' are events where various Astronomy Club members set up their telescopes for the public to look through.   You'll see several different types & designs of telescopes, and some of the nicer objects in the night sky at these events.   If you would like to learn more about astronomy,  plan on attending as many of these sessions as you can . . . especially if you're thinking about purchasing a telescope!!

Lights Out / Earth Hour - Saturday, March 26, 2022 / 8:30-9:30 PM Local time!

Switch off all your lights for one hour at 8:30 Local Time.

On Earth Hour hundreds of millions of people, organizations, corporations and governments around the world will come together to make a bold statement about their concern for climate change by doing something quite simple—turning off their lights for one hour.  In the U.S. where we are already feeling the impacts of climate change, Earth Hour sends a clear message that Americans care about this issue and want to turn the lights out on dirty air, dangerous dependency on foreign oil and costly climate change impacts, and make the switch to cleaner air, a strong economic future and a more secure nation.

Participation is easy.  By flipping off your lights on at 8:30 p.m. local time you will be making the switch to a cleaner, more secure nation and prosperous America.  Find out what else you can do to get involved including leading the Earth Hour movement in your community.

The GLOBE at Night program is an international citizen-science campaign to raise public awareness of the impact of light pollution by inviting citizen-scientists to measure their night sky brightness and submit their observations to a website from a computer or smart phone. Light pollution threatens not only our “right to starlight”, but can affect energy consumption, wildlife and health. The GLOBE at Night campaign has run for two weeks each winter/spring for the last six years. People in 115 countries have contributed 66,000 measurements, making GLOBE at Night one of the most successful light pollution awareness campaigns.

Check out the new web application data submission process. The GLOBE at Night website is easy to use, comprehensive and holds an abundance of background information. The database is usable for comparisons with a variety of other databases, like how light pollution affects the foraging habits of bats.

Once again the GLOBE at Night Team would like to express their thanks to all the participants who contributed measurements locally to make a global difference.

 

Globe at Night measurement reporting period has started, check the Globe at Night Reporting web site  for the results!
