UMass Amherst Campus

Handicap access available
Free admission

The public is invited to witness the sunset associated with the autumnal equinox among the standing stones of the UMass Amherst Sunwheel. The event marks the astronomical change of seasons when days and nights are nearly equal in length in the Northern Hemisphere.

At the gatherings, UMass Amherst astronomer Stephen Schneider will discuss the astronomical cause of the Sun’s changing position during the hour-long gatherings. He will also explain the seasonal positions of Earth, the Sun and Moon, and answer questions about astronomy, such as how do the phases of the Moon relate to the times it rises and sets? and why are days and nights not precisely equal on the equinox?


The UMass Amherst Sunwheel is located south of McGuirk Alumni Stadium, just off Rocky Hill Road (Amity St.) about one-quarter mile south of University Drive.
