Located on the campus of Foothill College in Los Altos Hills, California, Foothill College is operated by the Peninsula Astronomical Society, and offers weekly public astronomy programs on Fridays and Saturdays. The observatory is staffed by knowledgeable PAS members who volunteer to conduct these popular weekly events.
Public events are free of charge, and are open to visitors of all ages. However, please note that the observatory is closed when it is cloudy.
Foothill Friday Evening Program
Every clear Friday evening from 9:00 p.m. until 11:00 p.m.
Visitors can view the wonders of the universe through the observatory’s computer-controlled 16-inch Schmidt-Cassegrain telescope. Views of objects in our solar system may include craters and mountains on the moon, the moons and cloud-bands of Jupiter, or the rings of Saturn!
The choice of targets for any evening’s viewing depends on the season and what objects are currently in the sky. On clear, dark, moonless nights, the telescopes give visitors views into the deeper reaches of space. Star clusters, nebulae, and distant galaxies provide dramatic demonstrations of the vastness of the cosmos.
Since we are still dealing with COVID in the Bay Area, we are adopting the following guidelines to enable safe operation of the Observatory for both our public visitors and our PAS operators. We ask that visitors please agree to complying with these guidelines before visiting the Observatory, and to direct any questions to email@example.com.
COVID-19 ATTENDANCE GUIDELINES
The COVID and masking policy for Foothill Observatory is the same as that of Foothill College per their Health & Safety information page: Vaccinations are required and masking is strongly encouraged for visitors to the Observatory. We thank you for your efforts to help keep everyone healthy so that we can continue to offer these free observing events to the public.
Foothill Saturday Morning Program
Every clear Saturday morning from 10:00 a.m. until noon
Visitors to these daytime programs can view details of the sun through our special safe solar filters. 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).
