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

Next Star Party

March 24th & 25th

Hey! Our first spring star party of the year is coming up soon! Join us at GMARS to enjoy the crisp, clear and cool spring nights of the southern California desert. Our GMARS facility has a house, bathrooms, a kitchen—all the comforts of home!

GMARS star parties begin on 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!

RTMC Astronomy Expo coming up in May!

The annual RTMC Astronomy Expo is just around the corner—Memorial Day weekend!

Fred Espenak is the world's premiere eclipse expert and he'll be at RTMC! Be there for his keynote presentation about the upcoming Total Solar Eclipse Across America!
