Welcome to the Peninsula Astronomical Society


Foothill Observatory Remains CLOSED to All Visitors

(Updated July 2021) Following guidance from the Santa Clara County Health Officer and Foothill College, PAS is extending the suspension of our Foothill Observatory Friday and Saturday public viewing sessions for the foreseeable future. We expect to resume operations once Foothill College reopens the campus. Please check back here periodically for the latest status, follow us on Twitter at @pastronimocal, or check our Facebook page.

The Peninsula Astronomical Society (PAS) is a group of Bay Area astronomy enthusiasts of all ages and backgrounds. We hold monthly meetings (always online, these days) featuring invited speakers and covering diverse topics in astronomy.
