Will the event be safe? Annual Meeting COVID Safety Protocols:

To protect our members, sponsoring vendors, and staff at the in-person meeting, proof of full vaccination will be required to complete your registration.

Please note that requirements may change based on updates from the CDC and the state of Massachusetts at the time of the meeting.

Concerns about planning ahead for the fall?

We understand that planning for future events with COVID ever present can be challenging, so we are prepared to take the entire Meeting online if state and federal restrictions prevent travel and in-person gatherings in November. All registration fees can be converted to online pricing and refunds made as needed. The hotel allows guests to cancel their reservations up to 48 hours in advance of their arrival date.

The hotel Group Rate for AAVSO is available until October 5, 2021, but the number of rooms is limited, so we advise you to book soon: book your group rate hotel room for the AAVSO Annual Meeting.
