The Great Lakes Association of Astronomy Clubs (or GLAAC for short) is a loose association of amateur astronomy clubs and educational institutions in Southeastern Michigan who have banded together to provide enjoyable, family-oriented activities that focus on astronomy and space sciences.

Our primary aim is to have fun by learning about astronomy and space sciences, educating others through talks and star parties, and sharing our knowledge and skills with others who share our interest like local schools, scouts, and other organizations.
