From their Web site:
We meet every Wednesday evening at 9:00pm Eastern (01:00 UTC DST; 02:00 UTC standard) on the Quadnet Array. Early check ins usually begin about 15 minutes before the start of the net.
Each week we discuss topics of interest to both amateur astronomy, and where astronomy and amateur radio intersect. The first Wednesday of each month is dedicated to those who are new to amateur astronomy, or those interested in becoming involved in the hobby. We also feature a weekly trivia question.
