The York County Astronomical Society (YCAS) will offer astronomy programs to the public on Saturday, July 15. The programs will be shown at John Rudy County Park, 400 Mundis Race Road, York.

Programs will include Solar and Radio Astronomy from 11 a.m. to 3 p.m. Society member Kerry Smith will present the program, as well as give attendees a peek into the future of the society's radio astronomy endeavors. Radio astronomy is the study of unseen radiated energy in the electromagnetic spectrum below visible light. By using radio astronomy, society members are able to study astronomical phenomena that are otherwise invisible.

"How to Buy an Astronomical Telescope" will begin at 1 p.m., and the latest James Webb Space Telescope results will also be presented informally from 11 a.m. to 1 p.m.

Those who have a telescope and are not sure how to use it may bring it to the observatory, and experts will be on hand to offer help between 11 a.m. and 2:30 p.m.

While the events are free and open to the public, donations will be accepted to help the society to continue to bring astronomical events to York County and surrounding areas.

If the sky is clear, all activities will occur as scheduled. If it is completely cloudy or raining, the indoor activity of a screened astronomical presentation will occur as scheduled. In the event of extreme weather, call 717-759-YCAS (9227) for notice of cancellation or visit http://www.facebook.com/AstroYork.
