Object name: ARP327
Designation(s): ARP327, HCG34,
ARP 327, also known as Hickson 34, is a small group of 4 galaxies headed by NGC 1875, a very large E2 galaxy with a possible AGN (Active Galactic Nuclei). Its redshift puts it at about 410 million light years. The other members have slightly different redshift distances but this is likely due to interaction among themselves. Since NGC 1875 is the big gorilla of the group I'll assume it is little bothered by the companions and thus its redshift is the best indicator of the group's distance.
