Welcome to the TCAA

Welcome to the Twin City Amateur Astronomers' web site.

Located in the twin cities of Bloomington and Normal, Illinois, the TCAA was formed in 1960 to share our love of astronomy. We love doing astronomy, and talking about it: so much so that sometimes it takes a good whack across the head to get us to shut up. Ouch!

On this site you can find out about our public observing sessions, held at our dark sky observatory southwest of Bloomington; our public presentations, which take place at a variety of venues usually in the Bloomington-Normal area; and even peruse our award-winning newsletter, The Observer.
