Commissions

Activities in the various astronomical sub-disciplines are mostly conducted by Commissions, coordinated through the IAU Scientific Divisions, steering the activities and evolution of one or more IAU Commissions.

The list below is that of the current Commissions, which will disappear at the end of the 2015 General Assembly in Honolulu. To replace them, a Call for Proposals for Commissions has been issued on June 15 (see http://www.iau.org/news/announcements/detail/ann14014/ and the enclosed links to the Submission Form, procedure, etc.), with Letters of Intent due on Oct.15.
