Arp 259 - Hickson 31
Arp 259 (NGC 1741) appears to be in the center of a train wreck. Part of Arp’s ‘Galaxies (not classifiable as S or E) - Irregular clumps’ class, it is located approximately 186 million light-years away in Eridanus.
Hickson 31 consists of NGC 1741 above and another six or seven galaxies around it. All appear to be between 181 and 186 million light-years away by redshift.
IC 399 is the ball galaxy located below the above. Some sources include it as the seventh or ‘G’ galaxy in HCG 31.
