Supernova 2004dj in NGC 2403

This page is devoted to information on Supernova 2004dj in NGC 2403.   Basic information on this SN, including the last reported brightness, on this Supernova can be found on the main page.  Information on the original web pages for many of these images can be found on the updates and links web pages.

Discovered by Koichi Itagaki (Japan).   This is the brightest supernova to appear in several years.   A spectrum shows it to be a type IIP found just after maximum brightness.   Thus, if you have any images of NGC 2403 taken in late July of 2004, they might be worth a second look.   Type IIP supernovae tend to last a long time.   2004A was still visible 8 months after discovery.   The Progenitor, Sandage 96 has been found in a Kitt Peak image.   We have a DSS Photometry reference image made by Odd Trondal.  Icon generated from Bright supernova observing group's 2004dj image.  This supernova is in the Constellation Camelopardalis.
