Saturday Morning Solar Observing @ Foothill

Foothill 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.
