Every First Friday of the Month

First Friday Stargazing gives anyone free access to the night sky using university telescopes and teaching equipment.

Weather permitting, experienced astronomers will provide a handful of telescopes of varying designs, give training on how each operates, and point to various astronomical objects that may appear in the sky for that given time of the year. If you have a telescope and do not know how to operate it, feel free to bring it and get instructions on its use.

The Curtis Vaughan Jr. Observatory is located on the 4th floor of the Flawn Science Building on the UTSA Main Campus. After exiting the elevator, look for the doors to the outside star party observation deck adjacent to the observatory. The public is encouraged to park in the nearby Ximenes Ave Garage.

Due to varying times of sunset throughout the year, event start times will vary.
