Arp 30 consists of NGC 6365 (UGC 10833, VV 232/a and others), the edge-on spiral interacting with UGC 10832 (NGC 6365B, VV 232b and others), the face-on spiral. These are in the ‘Spiral Galaxies – One Heavy Arm’ class. Arp didn’t realize that the heavy arm was another galaxy. It is up for debate if these two galaxies are actually interacting since NGC 6365 appears to be further away than UGC 10832.
