ResumoThe history of the unusual star Eta Carinae is reviewed. Photographic magnitudes obtained from plates taken at Riverview Observatory, 1935–1952, and from some early Sydney Astrographic plates, are listed. It is shown that the star had commenced to brighten by April, 1941. The brightening has continued since then, with fluctuations. The colour of the star is discussed.
