Past Monthly Meetings

Our free monthly meetings, on the 3rd Friday of the month at 7:30 pm in McDonnell Hall Auditorium at Washington University, feature a guest speaker who is typically a professional researcher in Astronomy or an Astronomy-related field. This is followed by one or more Astronomy-related field. A social hour with refreshments follows the meeting.

These meetings provide opportunities to meet the officers and members of SLAS and socialize with a diverse and knowledgeable group of like minded individuals. Meetings are free and open to the public.
