In Brief:

Noted  for:
Berto Monard has discovered twelve supernovas. He has discovered twelve of the thirteen supernovas that have been discovered from Southern Africa.
He is also credited as the first amateur astronomer to discover the afterglow of a gamma ray burst.

This is a private Observatory outside Pretoria. Berto Monard, an engineer at CSIR, owns it. This Observatory is dedicated to studying Cataclysmic  Variables (CV’s), mainly unstudied ones. Mr. Monard is also a member  of the Centre for Backyard Astrophysics (CBA); a global network of small telescopes dedicated to photometry of CV’s. Bronberg Observatory, also known as CBA-Pretoria is the only dedicated African participant of this network.

Historical background:


  • The  Observatory went into operation in 2001 and Mr Monard has discovered  three supernovas at this site. Jack Bennet in M83 made the only  other supernova discovery from Southern Africa, in 1968.
