Next Star Party

September 15th thru 17th

What?! No star party in August?! That's right. Many club members will be chasing the Great American Total Solar Eclipse! There's a chance that GMARS may be open on what would've been the star party weekend (August 19th and 20th) but we cannot make any guarantees at this point.

We'll be sure to have a star party as soon as the new moon doesn't coincide with a total solar eclipse! :-)

Nightfall 2017 is closer than you think! Check out this short video from the Anza-Borrego Desert State Park during last year's Nightfall. Also, browse through the 2016 Nightfall archives, then make your reservation for 2017 (scratch that... make your reservation now THEN check out the video and archives)!
