Arp 102, also collectively known as Zwicky’s Connected Galaxies, appears to be a set of three galaxies. UGC 10814 (VV 10a and others) is the main galaxy with the tail extending north. MCG+08-31-042 (PGC 60073, VV 10b and others) is the LSB galaxy right next to it. MCG+08-31-041 (PGC 60067, VV 10 and others) is the galaxy below the others with a faint bridge. All of these are located approximately 330 million light-years away in Hercules.
There’s also another odd galaxy to the left (east) of these designated as PGC 140772. It is very odd-looking and could be multiple galaxies interacting. I could not find any other information on it.
