Open House Hours

Public open houses are held on Sommers-Bausch Observatory's observing deck on Friday evenings at 8:00 p.m. (9:00 p.m. during summer when Daylight Savings Time is in effect) when University of Colorado classes are in session and when the skies are clear. See our Friday Night Open House Schedule for more information.

Sessions typically last from 1-3 hours, depending upon the weather, the quality of the night, and the enthusiasm and size of the crowd (if unsure of observing status call 303.492.2020). Our open houses are informal, so please stop by anytime after we open and stay as long as you wish.

There is no charge for the Observatory's Open House nights ... the stars are free to everyone!
