About us
The Peninsula Astronomical Society (PAS) is an SF Bay Area astronomy club of enthusiasts of all ages, backgrounds, and experience. One thing that we all have in common is an interest in the night sky!
The PAS frequently hosts astronomy talks and events, and also runs the public Friday night and Saturday morning observing programs at Foothill Observatory on the Foothill College campus in Los Altos, California. Learn more about us, our programs, and public observatory openings at pastro.org.
Joining this Meetup group will keep you posted on public talks and events that are free of charge and do not require being a member. However, if you're interested in astronomy, we encourage you to become an official PAS member! Get the details on our PAS Membership page. Membership is only $25 per year, has many benefits, and directly supports public events.

Saturday Morning Solar Observing @ Foothill
Foothill College Observatory, 4100 Perimeter Rd, Los Altos Hills, CA, USFoothill Observatory is open for public solar observing on CLEAR Saturday mornings from 10:00 a.m. until 12:00 p.m.
NOTE: You need not RSVP here to attend; just come by!
Visitors to these daytime programs can view details of the sun through our special and safe solar filters, and dedicated solar telescope. We are able to provide spectacular views through both white-light and hydrogen-alpha (0.6 Angstrom) filters.
Visitors can inspect two different layers of the sun –– the photosphere and the chromosphere. Depending on solar activity, guests may see sunspots (giant cooler areas on the sun’s surface), solar prominences (huge flame-like eruptions), and solar flares (titanic explosions).

IN CASE OF POOR WEATHER
If weather conditions are not suitable for observing (clouds, rain, etc.), the observatory may not open at all -- or may close early. In such cases, this Meetup event status is not updated, so check the weather before coming by.
