Commission 41: History of Astronomy

Following the Sydney General Assembly, the membership of C41 stood at 352, of whom, at the time of writing, three are known to have deceased. Since the formation of the Inter-Union Commission for the History of Astronomy (ICHA) prior to the Sydney General Assembly, C41/ICHA has subsequently acted, in effect, as an integrated Commission with a single OC. In this triennium the C41/ICHA OC made strong efforts to clarify and simplify the controversial issue of admitting non-IAU members to the ICHA. After prolonged and active consultation, the OC approved the document "Procedures for Admitting non-IAU members to the ICHA" and the OC Secretary Prof. Clive Ruggles officially presented this document to the history of astronomy community in C41/ICHA Newsletter no. 6. It is subject to ratification by the C41/ICHA Business Meeting in Prague in 2006.
