Another LOSS discovery. This one has an interesting history.
2000ch started out as a galactic
variable, then
after its red shift was measured became an extra galactic nova.
Next, because of it's brightness (which is brighter than a Nova can get)
it got reclassified subluminous type IIn supernova. Finally it
appears that this may be an Eta Carini type explosion, similar to
1999bw, and
1997bs.
