Monday Twilight Sessions

  • Monday sessions are held each week, weather permitting, during the fall and spring semesters (see schedule below).
  • The start time for Monday sessions is determined by the approximate end of twilight for that month.
  • Each session runs one hour, and visitors may stay for all or any part of the entire period
  • Note Eastern Daylight Savings Time (EDT) ends on the first Sunday of November and resumes on the second Sunday in March.

Reservations are not required, but are requested so that we know how many people to expect and so that we can inform you if the Widener Observatory is closed due to inclement weather.
