Open Houses

Observatory Open House Schedule:

The University of Illinois Astronomical Society frequently holds observing sessions at the University's historic observatory. These sessions are open to the public free of charge. Visitors have the opportunity to gaze through the original 12" refracting telescope, as well as several smaller scopes. For more information on the observatory, take the ObservaTour.

The Observatory will be open to the public at the following times for viewing (weather permitting, must have mostly clear skies), and depending on the availability of trained club members to run the open house viewing sessions.

The usual open house schedule is for the first Friday of the month. If it's cloudy, then try again the following Friday if the weather looks good.
