NGC 3254 is a spiral galaxy in the constellation Leo Minor. It was discovered on March 13, 1785, by the astronomer William Herschel.[4] It is a member of the NGC 3254 Group of galaxies, which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the right edge of the Virgo Supercluster.[5]
Two supernovae have been observed in NGC 3254:
- SN 1941B (type unknown, mag. 15.1)[6][7] was discovered by Josef J. Johnson on 25 March 1941.[8] [Note: some sources incorrectly list the discovery date as 28 March 1941.]
- SN 2019np (type Ia, mag. 13.0) was discovered by Kōichi Itagaki on 9 January 2019.[9] This supernova was the brightest observed in the year 2019.[10]
