The public is invited to witness the summer solstice sunrise and sunset among the standing stones of the UMass Amherst Sunwheel Monday, June 20 at 5 a.m. and 7:30 p.m. This Sunwheel event marks the astronomical change of season when days are longest and nights are shortest in the Northern hemisphere. Heavy rain cancels the events.
