Our ties to local amateur societies are strong. The Mineralogical Society of Pennsylvania holds its monthly winter meetings at the university, usually on the third Sunday of November through March. During the rest of the year, the Society conducts monthly field trips and mineral shows. After a mineral auction and a Saturday night banquet, there is a Sunday field trip. The Chester County Rockhounds Society usually holds its monthly meetings on the second Wednesday of the month.
Members make observations of planets, asteroids, comets, star clusters, nebula, and other galaxies.
Meetings include a presentation by an invited speaker or the demonstration of an astronomical project by one of the members.
