Object name: ARP054
Arp 54 is a pair of galaxies, in Cetus 570 million light-years distant. Arp put in his category for spirals with small, high surface brightness, companions. The main galaxy is MCG-01-07-007 at magnitude 17.1 while the companion is 17.8 magnitude PGC 009107. To me, PGC 009107 is larger compared to the main galaxy than many that Arp put into his category for those with large companions. So is this really the galaxy he meant? It isn't on the arm but well away from it. There is a condensation on the end of the long arm that sort of points to PGC 009107. Is this the companion Arp meant? It better fits the description. But Arp apparently does mean PGC 009107 as the "small" companion as his note reads: "Arm toward companion split, contains nodule." NED classes it as SBc with HII emissions. Some call the pair an M51 type system due to the somewhat straightened arm leading toward the companion.
