SN 2004dj was the brightest supernova since SN 1987A at the time of its discovery.[citation needed
A light curve for SN 2004dj, plotted from AAVSO data[ 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 .[ 2] [ 3] 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.
