SN 2006jc was a hypernova that was detected on October 9, 2006 in the Galaxy UGC 4904. Two years earlier, the progenitor star produced a supernova impostor that was detected by Japanese amateur astronomer Koichi Itagaki. The star produced a high energy outburst that did not lead to stellar collapse.
The stars that are progenitors of these supernovae are extremely rare; there are probably only several dozen stars like this in a galaxy the size of the Milky Way galaxy. This means that 24 to 120 stars out of two hundred billion other stars are super luminous hyper giants like SN 2006jc's progenitor, and would be the population capable of producing such supernovae.
This type of progenitor star has a luminosity 1 to 6 million times that of the Sun. Its extreme rate of fuel consumption causes it to live a very short time, typically 3 to 5 million years. The star was probably of Class O, the hottest and most massive main sequence class. After perhaps 2 million years it became a bright giant, and then after another 500,000 years it had a violent outburst. Afterwards the star was unstable until its final explosion as a hypernova, two years later.
