Supernova 2006jc

Once upon a time there was an LBV in the far distant barred spiral galaxy UGC 4904. In October 2004 it erupted and already then was mistaken for a supernova. But this was only a mass ejection of one hundreth solar mass, typical for an LBV. Then, only just under two years later, it really exploded as a type 1b supernova. Possibly, shortly before its explosion it turned into a Wolf-Rayet star. The supernova was rather bright for its kind and even more unusual, because it happened a short time after a major eruption. So it gives an interesting new object of research to science.
