A magnitude 14.5 supernova, designated SN 1985A, was discovered in this galaxy on January 25, 1985. It was located3″ west and10″ south of the galaxy's nucleus,[8] and was later classified as atype Ia supernova.[9]
On August 31, 2013, a supernova event was reported at a position19″ west and21″ north of the core of NGC 2748. It was designated SN 2013ff and reached magnitude 15.2. Subsequent studies found a best match to atype Ic supernova.[10]
