But one of the most important benefits is what your membership does for the AAVSO. By supporting the AAVSO with a Sustaining ($150/year), Annual ($75/year) Teacher/Student/Limited Income ($37.50/year), or Developing Countries ($25/year) membership, you show us that what we do is important to you and to the science of variable star astronomy. Your membership helps us pursue original research, provide research support to professional astronomers, enable data collection and preservation and enable us to maintain our website, and support astronomy education and public outreach. And your participation in the community -- through attending meetings, participating in our discussion forums, serving on the AAVSO Council, contributing data to the AAVSO International Database, or submitting research papers to the Journal of the AAVSO -- helps to strengthen the connection between observers, researchers, and educators in the variable star community. Our members have made the AAVSO what it is today and we hope that you will be one of them!
Who Are AAVSO Members?
If you are:
- A variable star observer -- amateur or professional -- who wants to support the AAVSO above and beyond your contribution of data,
- A professional astronomer who uses AAVSO data and services, and wants to support the AAVSO and our mission to encourage variable star research,
- An educator who wants to share variable star astronomy with your students,
- A student just beginning your career in the sciences, or
- Anyone interested in the science and history of variable star astronomy, or in the collaboration of amateur and citizen scientists in astronomical research
then you are the sort of person who belongs in the American Association of Variable Star Observers! From its earliest days, the AAVSO has been made up of both amateur and professional astronomers, including some of the most important and influential astronomers of the 20th and 21st Centuries. Today, the AAVSO membership numbers over 1000 amateur and professional astronomers all over the world devoted to variable star research -- and you should be one of them! We need you to support the work that the AAVSO does in variable star astronomy, and to contribute your knowledge, skills, and expertise to further our mission. Please consider joining today!
