Every two years the Society holds a symposium where a variety of astronomy-related papers are presented, both by invited guest speakers and from the membership.

This year is the 200th Anniversary of the establishment of “the Royal Observatory at the Cape of Good Hope”, now known as the South African Astronomical Observatory (S.A.A.O.)  in Cape Town. A commemorative symposium is being organised by the S.A.A.O. The Society is not hosting a  symposium in 2020 but support and assist the S.A.A.O. in their symposium. For more information go to

The first symposium was held in 1992, in Cape Town. Visit the ASSA Symposia archives page for reports and photos of previous symposia.
