Next Star Party

July 29th & 30th

There's no way around it—the next GMARS Star Party is going to be HOT! And the temperatures will be high too! With highs over 100°F it'll be nice to hang out in the house(s) till the sun goes down. And there's a slight chance of a thunderstorm so keep your eyes and ears peeled.

GMARS star parties start on Friday afternoon/evening and go through Sunday morning. Be sure to join us Saturday evening for our Star-B-Q! Get more info by clicking the link below.

Did you miss the May 9th transit of Mercury across the face of the Sun? Check out Daniel Perry's video of his weekend trip to GMARS featuring the full transit (sped up, of course).
