Commission C3 History of Astronomy

Meetings

No Commission C3 meetings have been scheduled for the near future. We are developing plans to organize a two-day meeting at the occasion of the XXXIIth IAU General Assembly in August 2024 in Cape Town. The theme will cover a range of subjects on the history of astronomy in South Africa. The topics are entirely within the remit of Commission C3, and are also of interest to other IAU Commissions and Working Groups. The meeting will concentrate on people, instruments, and projects during the last two centuries  ̶  i.e., the period since the establishment of the Royal Observatory at the Cape of Good Hope.
