Please be advised: the AAS is currently upgrading its constituent database system; as such, sections of the website related to winter meeting abstract submissions, donations, and membership are inaccessible.


Timing: The upgrade will begin at noon EDT on Thursday, 15 August. We expect the donation and membership pages to be restored by Monday, 19 August, at the latest. The abstract system will be back online by Wednesday, 21 August.

Actions affected: membership renewal; donating; submitting AAS 235 abstracts and splinter meeting proposals; viewing and updating your member profile and communication preferences; searching the online membership directory.

New Looks

When you log in to renew your membership or register for the 235th AAS meeting in Hawaii, things will look a bit different. That’s because we’re also working on a full website redesign to launch in September.

We apologize in advance for any inconvenience to you during the downtime, and we are sure the final result will be welcomed by all. As always, if you have questions or concerns, please contact the membership team at
