Next GMARS Star Party

October 13th – 15th

There's an annular solar eclipse on Saturday, October 14th! Many club members will be traveling to the center line rather than heading to GMARS (it'll only be a 71% partial eclipse from SoCal).

We won't be holding our normal star party events (no Star-B-Q) at GMARS but the telescope field and houses will be available and open. Availability of the houses is depenedent on the presence of a keyholding member (one will be present over the weekend).

Here's the latest view from the GMARS all-sky camera, which is mounted on the GMARS West property next to the weather station and picnic area.
