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.
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 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.
