MASKS REQUIRED

CU Boulder has returned to requiring masks in public indoor spaces (including the observing deck) regardless of vaccination status as of August 13, 2021.

Practice good hygiene during your visit by washing your hands or using the sanitization stations. Please respect your fellow visitors. Some may prefer to continue to social distance as we all adjust to the changes.

Open houses are only held when the skies are clear. If you're not sure if we'll be open, check out our local weather or call us for an observing status at 303-492-2020. 

There is no charge for the Observatory's Open House nights ... the stars are free to everyone! Sessions typically last from 1-3 hours, depending upon the weather, the quality of the night.
