The public is invited to join astronomers at the UMass Sunwheel, beginning at 5:15 a.m. on Thursday, June 10, to safely observe an eclipse of the sun. A crescent-shaped sun will rise in the northeast, and it will remain partially eclipsed by the moon until 6:33 a.m. An eclipse occurring at sunrise is a rare and beautiful event. Because the eclipse will occur just 10 days before the summer solstice, the Sunwheel’s standing stones will lend extra significance to the moment.
