Welcome to the Astronomy Society of Bloemfontein City

ASSA Bloemfontein Centre is a group of active enthusiasts meeting on a regular basis to discuss their interest in astronomy. Whether a member's interest lies with armchair astronomy, deep sky observations, astrophotography, solar or lunar studies, telescope making or astronomical history, they all share the need to expand their knowledge in the subject and enjoy astronomy as a humble and fulfilling hobby.

This non-profit club is centered around the City of Bloemfontein, in South Africa. Please contact us for more information: membership is open to anyone, regardless of how much you know about astronomy! Further reading on who we are.
