Abstract
The historical and present light curve based on a decade of photometric monitoring of the variable star η Car is discussed and an interpretation of its behavior is given. The light variation is probably caused mainly by the changing characteristics of the envelope. The light variation during the last decades is due to the fact that the central star oscillates in temperature about a few thousand degrees with a time scale of 2 to 3 yr.
