The George Mason University Observatory at the Fairfax Campus building Research Hall (see campus map here) officially opened 24 January 2007. There are a number of informal night sky observing sessions scheduled throughout the regular semester. Attendance at these sessions is open to all students, faculty, staff and the interested public. The primary telescope used in the observatory atop the pier is the 0.8m (~32") Ritchey-Chretien telescope. There is a 12 inch Schmidt-Cassegrain telescope used on the patio that provides good views of the sky as well. We still possess the 6" refractor originally built by GMU students in 1975 (it is on display in the glass alcove).

Please note that the observing session will be canceled if the sky is more than half overcast one hour before the session is scheduled to begin, or if it is too windy (>20mph) to open the observatory dome. If in doubt, check weather forecast here or here, and check the Clear Sky Chart for the area . HOWEVER, ALL TALKS WILL TAKE PLACE REGARDLESS OF THE WEATHER.


The location of the observing sessions is the observatory at Research Hall. Access to the observatory is limited. Guests will be met in Research Hall lobby by the main elevators. If you are late, you can stay by the elvators and someone will meet you, after you call the observatory at 703-993-9558 and have been acknowledged by observatory personnel.
NOTE: The observatory deck has very rough flooring. Guests are advised to WEAR ONLY CLOSED TOED SHOES. NO SANDALS or other open toed shoes.
