SN 2004dj
- REDIRECT Template:Infobox astronomical event
SN 2004dj was the brightest supernova since SN 1987A at the time of its discovery.[1]
This Type II-P supernova was discovered by Japanese astronomer Kōichi Itagaki on 31 July 2004. At the time of its discovery, its apparent brightness was 11.2 visual magnitude; the discovery occurred after the supernova had reached its peak magnitude.[3][4] The supernova's progenitor is a star in a young, compact star cluster in the galaxy NGC 2403, in Camelopardalis. The cluster had been cataloged as the 96th object in a list of luminous stars and clusters by Allan Sandage in 1984; the progenitor is therefore commonly referred to as Sandage 96. This cluster is easily visible in a Kitt Peak National Observatory image and appears starlike.
