SN 2013ej is a Type II-P supernova in the nearby spiral galaxy Messier 74 (NGC 628).[1] It was discovered by the Lick Observatory Supernova Search on July 25, 2013, with the 0.76 m Katzman Automatic Imaging Telescope, with pre-discovery images having been taken the day before.[2]
Supernova 2013ej was noted for being as bright as 10th magnitude.[3]
SN 2013ej was compared to supernovas SN 2004et and SN 2007od.[4] Based on various observations it has been theorized that the supernova originated from a red supergiant star that went supernova.[5]
