IC 4271 is a spiral galaxy located some 800 million light-years away in the Canes Venatici constellation.[1] It is 157,000 light-years in diameter.[2] IC 4271 was first located on July 10, 1896, by Stephane Javelle, a French astronomer.[2] It hosts a Seyfert type 2 nucleus, containing an acceleration disc around its supermassive black hole which releases large amounts of radiation, hence its bright appearance.[3][4] IC 4271 appears to be interacting with its smaller neighboring galaxy, PGC 3096774.[2][5][6]

Both galaxies form Arp 40.[7][8] In the Atlas of Peculiar Galaxies created by Halton Arp, they fall under spiral galaxies that have companions with low-surface-brightness.
