NGC 3294
Galaxy in the constellation Leo Minor
From Wikipedia, the free encyclopedia
NGC 3294 is a spiral galaxy in the constellation Leo Minor.[5] It was discovered by William Herschel on Mar 17, 1787.[9] It 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.[10] The galaxy is located at a distance of 98[4] million light years and is receding with a heliocentric radial velocity of 1,586 km/s.[3] The morphological class of NGC 3294 is SA(rs)bc,[7] which means this is a spiral galaxy with no central bar (SA), an incomplete inner ring structure (rs), and moderately wound spiral arms (bc).

This galaxy has been host to a pair of supernova events:
- SN 1990H was discovered by Saul Perlmutter and Carlton Pennypacker on 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]
- SN 1992G was discovered by Shunji Sasaki on 14 February 14 1992, 27″ east and 10.5″ south of the galaxy's nucleus.[13] This was determined to be a type Ia supernova.[14]
