Foothill Observatory is open for public viewing 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 will see sunspots (giant cooler areas on the sun's surface), solar prominences (huge flame-like eruptions), and solar flares (titanic explosions).
The public viewing programs at Foothill are free of charge and are open to guests of all ages. Please note that the observatory is closed when the weather is cloudy. Also note that visitor parking permits are available from the machines in the parking lots for $3.00 (as of January 2012). Please do not park in spaces marked "Staff" or you will be ticketed!
Come to Foothill Observatory and join us in the exploration of our Universe!
