Nightfall Star Party!

Our next star party is at the Nightfall Star Party & Imaging Conference in Borrego Springs.

Nightfall Website

The GMARS telescope field will be available should you wish to party with the stars there instead. Please keep in mind that the house may not be open as most will be attending Nightfall.

A river of rain water flows through GMARS West on July 11, 2018.

Monsoonal rain on 7/11 put the "river" in Riverside Astronomical Society! GMARS received over 1" of rain that afternoon and the temperature dropped from 95° to 68° over the course of 2 hours! Click the image for a 1920x1080 version.
