Free star parties are held at the Lin Hall observatory every Wednesday night while OU is in session.

General Information

Every Wednesday night while OU is in session, the Physics and Astronomy department sponsors free public star parties on the roof of Lin Hall. A typical night could include a planet or two, binary stars, star clusters, or maybe one of the brighter nebulae. All ages are welcome, but we ask that younger children be under adult supervision at all times.


Lin Hall is located on the just south of the campus Bizzell Memorial Library. Look for the building with the silver dome on top. To reach the roof, enter the east stairwell and take the elevator to the 3rd floor.

Note: The new observatory is wheelchair accessible.


Viewing times change throughout the year, so please check this page (or our Twitter) for current observing times and weather cancellations. The final decision on weather cancellations will be made three hours before the scheduled start time at the latest.

History & Research

History of the Old Observatory

Built in 1939, with a 10 inch Newtonian reflector and a smaller 3.5 inch telescope, it was housed in a 16-foot dome atop what was at the time, the southernmost building on campus. In 1995, the original 10 inch telescope was replaced by a 0.4 meter (16 inch) Meade SCT. Currently the facility houses an 11 inch Celestron, numerous smaller 8 inch Celestrons, in addition to the main 16 inch Meade.


While the old observatory facilities were utilized by OKC and Norman proper for research purposes, the telescopes have since retired to be used for outreach and public service. During the time of research, professional photographic plates were taken in numerous surveys and detailed observation runs by students, professors, and researchers. Nearly 20,000 original photographic glass plates are still housed at the old observatory.

Construction of Lin Hall Observatory

With the completion of the new Chun Lin Hall building of research in late 2018, a new public observing facility was built atop the state-of-the-art building. The building, built to high vibration tolerance, will provide the best viewing experience for astronomical seeing and imaging. Atop the building, on the 3rd floor, rests a brand new 14in Meade SCT polar mounted telescope with a fixed imager, capable of remote observations and unprecedented astronomical images taken at OU. In addition to this research grade telescope, 9 new 8in telescopes were also installed with vertically adjustable stands to aid with public outreach and the numerous astronomy labs taught at OU. It is estimated over a hundred students use the telescopes each semester and over two-hundred community members join us for star parties. With the introduction of this one-of-a-kind facility, we can now provide the best service to the community and our fellow students. Clear skies!
