Arp 74

Arp 74 consists of UGC 1626 (PGC 8161 and others), the spiral at the center and Arp 74B (2MASX J02082216+4128061) the small galaxy below it. Arp includes these in his “Small, high surface brightness companions on arms.” While I could not find any information on distances, it is highly possible that Arp 74B is much more distant than UGC 1626 with no interaction at all. These are located about three degrees from NGC 891 in Andromeda.
