The Astronomical Society of Southern Africa (ASSA), formed in 1922, is a body consisting of both amateur and professional astronomers. The Council of ASSA meets in Cape Town. There are 8 autonomous centres throughout Southern Africa.
The Cape Astronomical Association was established in 1912, shortly after the 1910 appearance of Halley's Comet. Sydney Samuel Hough, HM Astronomer at the Cape, was chosen President. In 1918, the Johannesburg Astronomical Association was created, with RTA Innes, Union Astronomer, as President.In 1922 it was decided to merge the two Associations to form the "Astronomical Society of South Africa", after an invitation from the Cape Association.
