Monthly Lectures
The SFAA hosts lectures at two venues:
The Randall Museum

Mount Tam

Evening programs are held each Saturday between the new and first quarter moon from April through October. A talk by a professional astronomer, physicist, or space scientist begins in the Mountain Theater near the end of twilight and lasts about 45 minutes. These presentations are typically enhanced by beautiful images projected on a large screen. The audience is invited to ask questions at the end.
Immediately following each month’s lecture, the audience is invited to remain in the Mountain Theater for a brief Night Sky Tour by the Urban Astronomer, highlighting the prominent constellations, stars and planets visible in the night time sky, before enjoying the observing session (starparty) conducted by the San Francisco Amateur Astronomers in the Rock Springs parking lot.
Following the lecture, audience members are invited to the Rock Spring parking area to view through telescopes provided by members of the San Francisco Amateur Astronomers. The observing session (or “starparty”) lasts from 1 to 1 1/2 hours, depending on the seeing conditions and the size of the crowd.
