AAVSO Annual Campaign: 2021-2022

 Please click here to donate! 


Members and Friends of the AAVSO,

This year, we are celebrating our 110th year, a rarity for a non-profit organization. We could not have done it without your support. 

Guided by our mission “to enable anyone, anywhere, to participate in scientific discovery through variable star astronomy,” we have begun implementing the new strategic plan focused on three primary goals:

  • High Member Satisfaction


  •  Increased Organizational Impact


  •  Long-Term Financial Stability


In support of this plan, many new initiatives are underway, and we are already seeing positive results. We are dedicated to the growth and satisfaction of our membership, as well as the impact of our work on the scientific community.

Our membership has grown to over 1,400 individuals, representing a unique collaboration of professional and amateur astronomers, as well as others interested in supporting our work.

Your donation will help us to be even more successful so that a future generation can celebrate our 200th Anniversary!
