NGC 3370 (also known as UGC 5887 or Silverado Galaxy[1]) is a spiral galaxy about Script error: No such module "convert". away in the constellation Leo. It is nearly comparable to our Milky Way both in diameter with a D25 isophotal size about Script error: No such module "convert". comparing to the Milky Way Galaxy's Script error: No such module "convert". diameter, and as well as in mass (Script error: No such module "val".).Script error: No such module "Unsubst". NGC 3370 exhibits an intricate spiral arm structure surrounding a poorly defined nucleus. It is a member of the NGC 3370 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.[2]
History
NGC 3370 was likely discovered by William Herschel, who provided it with the designation II 81.[3] His son John later designated it 750. William Herschel cataloged I 80 to NGC 3348[3] before and II 82 to NGC 3455 after NGC 3370.[3]
The object has a surface brightness of 13 and a position angle (PA) of 140°.
On November 14, 1994, S. Van Dyk and the Leuschner Observatory Supernova Search discovered a supernova in NGC 3370 at 10h 44m 21.52s +17° 32Template:Prime 20.7Template:Pprime, designated SN 1994ae.[4] SN 1994ae was a type Ia supernova, and one of the nearest and best observed since the advent of modern digital detectors.[5] The maximal light of the supernova was estimated to have occurred between November 30 and December 1,[6] peaking at visual magnitude 13.[4]
