What we're about

The Astronomical Association of Northern California is a non-profit corporation for fostering astronomy in Northern California. We serve as a central location for member astronomy clubs, amateur astronomers and professionals throughout the area to share information about events and news regarding their organizations.

Clubs and other interested organizations: Appoint a PR person to post events here. Once your group is a supporting member - a sponsor link to your organization's web-site will be added here - as seen in the left column of this page.

Everyone is welcome to join the AANC Meetup group, receive notices of events posted in your area or bay-area wide. If you would, please let others who might be interested in local astronomy know about this Meetup Group. When you respond to one of the AANC posted Meetups, you are given an option to share it on other social networking sites such as Facebook and Twitter. Please, spread the word!
