Public Events » Open House Schedule

Our Open House events are held on Friday nights at the Tombaugh Observatory on the NMSU campus (click here to see its location). They occur roughly once per month, near the time of the first-quarter Moon from September through May, and often during the summer as well. Each evening program begins with a short presentation, followed by guided observing through telescopes. You may call 646.4438 for more information about the program for a specific month. Children are particularly encouraged to attend!

If the weather looks cloudy or stormy on the afternoon of an Open House Event, please call 646.6278 to confirm that the observatory will be open that evening. We cannot operate the telescopes under conditions of heavy clouds, high humidity, or rain.

Please check back in September for our Fall 2015 open house schedule.
