About once a month during the spring and fall semesters, Wellesley students and faculty open the Observatory to members of the public. Visitors are invited to take a tour, listen to talks, and (when clear) look through our 6-inch and 12-inch telescopes.
Public nights are free and will be held regardless of weather conditions. No reservations are required.
Children must be supervised by their grownups. We regret that we cannot accommodate groups.
If you are visiting us for a Whitin Night, please know that the Observatory driveway and circle are closed to vehicles after sunset. (more information)
Fall 2015 -- check here for dates or watch for them on Facebook.
Talks and activities happen at the scheduled time rain or shine, and telescopic observing only if skies are clear.
