The GAU was created in 2009 for the purpose of sharing the subject of amateur astronomy and the night sky without the administrative burden that volunteer registered non-profit astronomy organizations experience. 

There are no members, no dues, no formal structure, and no expectations other than to enjoy the night sky and share the experience with others. 

The GAU hosts informal astronomy events, coffeehouse meetings, and observing sessions. 

The GAU is also available for free public lectures and static displays on amateur astronomy for all age groups.
