Viewing of the Sun: From Star to Red Giant to White Dwarf

Date: Sunday, September 17th
Time: 11:00am - 1:00pm
Place: Foothill Observatory
12345 El Monte Road, Los Altos Hills
Cost: $15 for Member, $20 for Non-Member, $10 for Recent Graduate

Formed nearly 4.6 billion years ago, the Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System.

Join Harvard alumni, families, and guests at the Foothill Observatory for an exclusive, educational viewing and lecture about the Sun. Alumni can view details of the sun through the observatory’s special eye-safe solar filters. Alumni will be provides with spectacular views through both white-light and hydrogen-alpha (0.6 Angstrom) filters. Attendees can inspect two different layers of the sun—the photosphere and the chromosphere. Depending on solar activity, alumni will see sunspots (giant cooler areas on the sun's surface), solar prominences (huge flame-like eruptions), and solar flares (titanic explosions).  There is even the chance to telescopically view well-placed planets despite the daylight using the 16-inch computer-controlled Schmidt-Cassegrain reflector and a new hydrogen-alpha solar telescope.


To aid in the planning of this event, RSVP by September 10th. Please include the first and last name, and Harvard class (if applicable), of each attendee. If any attendee is less than 14 years, please let us know that, too. RSVPs and payments received after September 10th are welcome, but must pay a $5 administration fee. Please register early!
