Inclement Weather Policy

Monday Twilight Sessions

If the weather conditions are poor (because of clouds or rain), the Monday Twilight Sessions will not be held. Please make a reservation for another Monday session.

Friday Sessions

If the weather conditions are poor (due to clouds or rain), visitors are still welcome to view the facilities and see a planetarium show. However, if the weather conditions are severe or hazardous (thunderstorms, snow, ice storms), the entire Friday Evening Session will automatically be cancelled.

When weather conditions are uncertain, a decision will be made before 4 p.m. as to whether a session will be cancelled.

Please also refer to the Widener University Clear Sky Chart, which gives an hour-by-hour prediction of when to expect clear skies for astronomical observing.
