This galaxy has been host to a pair of supernova events. SN 1990H was discovered April 9, 1990 at a position 12″ west and 1″ south of the galactic nucleus.[11] The spectrum and light curve resembled a type II core-collapse supernova similar to SN 1987A.[12] A scan two years later on February 14, 1992, SN 1992G was imaged 27″ east and 10.5″ south of the nucleus.[13] This was determined to be a type Ia supernova.[14]
