Arp 215 (NGC 2782, UGC 4862, VV 1268 and others) is a Seyfert (I see references to a type 1 and 2) spiral located approximately 126 million light-years away in Lynx. It is suspected that the current form was the result of a galaxy merger in the past. Arp lists it in his category galaxies with adjacent loops.
The galaxy at the bottom left is UGC 4872.
