The AAVSO organizes an Annual Meeting each fall. Meetings are held in different locations each year to make it more accessible for members and observers from across the country to attend. Anyone interested in the AAVSO is invited and encouraged to participate in our meeting.

Each meeting includes presentations by both invited keynote speakers, and AAVSO members and observers whose presentation abstracts have been accepted for inclusion in the agenda. Presentation topics include variable star research and discoveries; astronomy education and diversity experiences, studies, and solutions; and variable star history.
During lunches and coffee breaks, in-person meeting attendees catch up and exchange ideas. The AAVSO Executive Director, board members, and JAAVSO editor-in-chief host a Membership Meeting that is broadcast online and open to the public. They report on the activities of the AAVSO, financial status, and new developments within the organization.
Prior to 2021, the AAVSO also hosted an additional meeting in the spring. These and the fall meetings are listed below.
