Monday Twilight Sessions

Monday evening sessions are held each week, weather permitting, during the fall and spring semesters (see schedule below). Each session lasts about one hour, although visitors need not stay for the entire period.

The start time for Monday sessions is determined by the approximate end of twilight for that time of year.

Note that Eastern Daylight Savings Time (EDT) ends on the first Sunday of November and resumes on the second Sunday in March. All dates in between are Eastern Standard Time (EST).

Group Requests

We consider requests for telescope viewing sessions for elementary and high school classes, Girl Scouts, or Boy Scouts, and other organizations. These are usually held on Monday nights, separate from the public session. The maximum number (adults and children) we can accommodate is 40.

Contact Theresa Sminkey at for more details.

Reserve a Monday Twilight Stargazing Session for yourself or your group.
