NGC 2748
NGC 2748 is a spiral galaxy in the northern circumpolar constellation of Camelopardalis, located at a distance of from the Milky Way. It was discovered September 2, 1828 by John Herschel. The morphological classification of SAbc indicates this is an unbarred spiral with moderate to losely-wound spiral arms. It is a disk-like peculiar galaxy with a stellar shell that is rotating about the main galactic axis. This shell was most likely formed through the capture and disruption of a dwarf companion. The galactic nucleus likely contains a supermassive black hole with a mass of, or 44 million times the mass of the Sun.
A magnitude 14.5 supernova, designated SN 1985A, was discovered in this galaxy on January 25, 1985. It was located west and south of the galaxy's nucleus, and was later classified as a type Ia supernova. On Aug. 31, 2013, a supernova event was reported at a position west and north of the core of NGC 2748. It was designated SN 2013ff and reached magnitude 15.2. Subsequent studies found a best match to a type Ic supernova. The discovery of a supernova impostor in this galaxy was announced February 10, 2015. During September 2017, the discovery of supernova SN2017gkk in host galaxy NGC 2748 was announced.
