NGC 3191 (also known as NGC 3192) is a barred spiral galaxy in the constellation Ursa Major. It was discovered on 5 February 1788 by William Herschel. It is located at a distance of about 400 million light years from Earth, which, given its apparent dimensions, means that NGC 3191 is about 115,000 light years across.

The galaxy has been distorted and interacts with a companion about 0.5 arcminutes to the west, a galaxy identified as KUG 1015+467. An extremely blue tidal bridge lies between them.[2] It was discovered by Gaia on 23 May 2017.

Supernovae

Three supernovae have been observed in NGC 3191: SN 1988B, PTF10bgl, and SN 2017egm. SN 1988B was discovered by P. Wild 10" north of the galaxy's center. On Jan. 18.94 and 21.85 UT, it was magnitude 15.5.[3] It was a type Ia supernova.[4] PTF10bgl (typeII-P, mag. unknown) was discoverd on 6 February 2010 by the Palomar Transient Factory.[5] SN 2017egm was identified as a Type I superluminous supernova. It is the closest supernova of this type observed and also the first to be found in a massive spiral galaxy.[6]
