Absolutely nothing happened in Sector 83 by 9 by 12 today.

Heads Up! (so to speak).

This coming Saturday, we will have a large number of Cub Scouts (First- through fifth-graders) at the Cernan Center.
I know that they will be eager to see what they can see though our eye-pieces, so please bring your light-buckets to show off, weather permitting.
Thank You in Advance!

The next General Meeting of the Chicago Astronomical Society will be on Saturday, February 28, 2026 at 17:00 CST Details!
