Upcoming Meetings


The 109th Spring Meeting - Joint SAS/AAVSO 2020 Symposium will now be held online! 

After much consideration, due to the health crisis, it was decided that the SAS/AAVSO-2020 Symposium will change to an “on-line” format. Please note the change in dates and times below.

This year's online-only Symposium will be structured in 2.5-hour daily sessions, from 1800 UT to 2030 UT (US time zones: start time is 11 AM PDT = 2 PM EDT), spread across five non-consecutive days:

  • May 30 (Saturday)
  • June 13 (Saturday)
  • June 14 (Sunday)
  • June 20 (Saturday)--includes the AAVSO Meeting: an update and discussion on our strategic planning initiative! 
  • June 21 (Sunday)

Register for the meeting.​


Each daily online session will feature technical presentations, audience Q&A, and a panel discussion with the presenters.

You should cancel your hotel reservations by contacting the hotel directly.

About AAVSO Meetings

The AAVSO usually organizes two meetings each year, one in the fall (usually late-October) and one in the spring (usually April or May). Meetings are held in different locations each year. This makes it more convenient for members and observers from different regions of the US (and abroad) to attend. Anyone interested in the AAVSO and its activities is invited and encouraged to participate in our meetings. 

AAVSO Annual Meeting 2018

AAVSO meetings provide members, observers, and interested guests with an opportunity to present their own research on variable stars and related topics. At each meeting a professional astronomer involved in variable star-related research is invited to give a guest lecture on his or her area of expertise. Time is generally allotted for an open discussion period where those in attendace are welcome to exchange ideas about observing, new techniques, problems, solutions, or any other topic that may come up. The Director of the Organization will also give the Director's Report to report on the activities of the AAVSO. AAVSO meetings also provide an opportunity for members, observers, and other attendees to get to know each other and the AAVSO Headquarters staff.

If you wish to give a talk at an AAVSO meeting please read our Speakers Guide for some helpful tips.

Please note that all attendees at the meeting are expected to follow our Non-Discrimination and Non-Harassment Policy and Event Conduct Policy. Participation in the meeting is taken to signify your acknowledgment that you have read these guidelines/policies and your agreement to adhere to them.
