Holiday Potluck and Awards Dinner

Sunday, December 11, 2022
EAS Holiday Potluck
6:00 PM
Kepler/Copernicus Room (a.k.a. Classrooms 3 & 4)
Chabot Space and Science Center
Once again, EAS will be having its holiday potluck party on Sunday, December 11, at 6 PM in the Kepler-Copernicus room at Chabot. This event is always a lot of fun and gives us a chance to chat and get to know everybody better. Ray Howard will provide a trivia quiz and we will have door prizes and annual awards. 

EAS will provide the turkey, but the remaining meal is pot luck, provided by you, the members.  In order to prevent food quantity problems (too much of one type of food, too little of another type of food), we request that everyone stick to the following food assignments:

Last name begins with:

A to I: Salads, Appetizers, and Breads. 

J to S: Entrées, Sides, and/or Vegetables.

T to Z: Desserts and Beverages. 

Please RSVP by Tuesday, December 6 to library@eastbayastro.org with number of people attending and what you are planning to bring.  EAS will provide a turkey from Harry’s Hofbrau.

Telescope Makers’ Workship

The Telescope Maker’s Workshop is one of few regularly scheduled such workshops in the world! Every Friday from 7 to 10 PM, amateur telescope makers from the bay area meet at the Chabot Space & Science Center and learn how to grind, shape, polish, and figure mirrors for reflecting telescopes, under the guidance of EAS volunteers. The workshop is free; participants pay only for the mirror blanks and grinding tools, which generally cost between $100-$300, depending on the size of the mirror. All the instruction, grinding grit, testing equipment, and camaraderie is free of charge! For more information, email Richard Ozer at pres@eastbayastro.org, or come by the workshop any Friday to see what it’s all about.


In person events are more limited because of COVID, but are being scheduled for schools and other community institutions. Contact us also for possible virtual events, or visit http://www.chabotspace.org for scheduled public virtual telescope viewing events]

EAS sends volunteers to schools, libraries, and anywhere curious aspiring astronomers gather. EAS volunteers bring their own equipment or borrow telescopes. Students, parents, and teachers are always thrilled to look through the telescopes and ask questions. You’ll meet all sorts of interesting people and provide a unique and inspiring experience to kids and parents who may have never looked through a telescope before. Find our next event on the calendar above.

Inquire about and request visits by e-mailing EAS Outreach Coordinator Raymond Howard at outreach@eastbayastro.org. Visit our outreach page to find out about upcoming events.
