Public Radio Astronomy

Radio Astronomy, Solar Observing and Weather, and Telescope Clinic at Astronomical Society

The York County Astronomical Society (YCAS) has decided to cancel all public programs until there is an effective and widely distributed vaccine available.

Thank you for your understanding and please stay safe.



Formed in 1989, the non-profit York County Astronomical Society aims to promote interest, public education, and advancement of the science of astronomy. In addition to planetarium shows, the society presents regular public sky watches and astronomy classes.
