Arp 202 consists of NGC 2719 (UGC 4718, PGC 25281 and others) the long galaxy above MCG+06-20-018 (NGC 2719A, PGC 25284 and others), the irregular galaxy below it. Part of Arp’s “Galaxies not classifiable as E or S – Material ejected from nuclei” class, these are located approximately 166 million light-years away in
Lynx.
NGC 2724 (UGC 4726, PGC 25331 and others) is the low-surface-brightness spiral to the left of center. I’m surprised it didn’t end up on Arp’s list.
