AMERICAN ASTRONOMICAL SOCIETY ANNUAL CONFERENCE

The AAS annual winter meeting started in 1899 – this is our 125th year of hosting the world’s largest and most prestigious meeting & exhibits on astronomical science.

Only recently did the board of directors, in association with Sky & Telescope, agreed to open the meeting to amateurs…we are thrilled that the meeting is open to amateurs and that the board created a separate / discounted membership / meeting registration.

Scientists and businesses attending will pay a registration fee of $400-$900 per person depending on membership, government vs. non-government, etc.

To attend the AAS annual winter meeting, it is two-step process:

1. Join AAS as an Amateur Affiliate member
2. Register for the AAS 245 meeting as an Amateur Affiliate

Amateur Affiliate

Amateur Affiliates are those who advance or support the astronomical sciences through research, public outreach/communication, or advocacy but who do not depend on an astronomical research and/or educational institution as their primary source of income and who do not qualify for any other class of membership. Applicants must be members of a recognized organization of astronomy enthusiasts, for example, an astronomy club, a citizen science project, an advocacy group, or an association that facilitates professional-amateur collaboration.
