Next star party of the Riverside Astronomical Society–The best astronomy club in southern California!

Next Star Party

February 16th & 17th

We've had a fairly mild winter so far at GMARS with low temperatures mostly in the 40s. But that could change by the time our next star party rolls around—so always keep an eye on the weather before coming out to GMARS!

GMARS star parties start Friday afternoon/evening and wrap up on Sunday morning. Be sure to join us for the potluck Star-B-Q on Saturday afternoon (roughly 60-90 minutes before sun down). We provide the dogs, burgers and fixings. You provide a sidedish, dessert or beverages!

On January 9th, GMARS received almost 1" of rain. Shortly before the rain began to fall, this rainbow appeared and was captured by the GMARS North View webcam.
