Monthly Star Party at GMARS

February 21st – 23rd

Join us at GMARS for our monthly star party. The Moon will be new, which means the skies will be dark. Don't forget to come prepared for cold temperatures! 🌵 🥶 🌚 ⭐ 🔭

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 (if you want to)!
