NGC 214 is a spiral galaxy in the northern constellation of Andromeda, located at a distance of 194 megalight-years from the Milky Way.[3] It was discovered on September 10, 1784 by William Herschel.[6] The shape of this galaxy is given by its morphological classification of SABbc,[4] which indicates a weak bar-like structure (SAB) at the core and moderate to loosely-wound spiral arms (bc).

On July 19, 2005, a magnitude 17.4 supernova was detected at a position 16″ west and 2″ north of the galactic nucleus. The object was not visible on plates taken July 2, so it likely erupted after that date.[7] Designated SN 2005db, it was determined to be a type IIn supernova based on the spectrum.[8] A second supernova event was spotted from an image taken August 30, 2006, at 43″ west and 11.3″ south of the nucleus. It reached magnitude 17.8 and was designated SN 2006ep.[9] This was determined to be a type-Ib/c supernova.[10]
