Object name: ARP329
Designation(s): ARP329, HCG55,
Arp 329 aka Hickson 55 is yet another chain of elliptical galaxies Arp logically put in his Group Character: Chains of galaxies class. Also known as UGC 6514 1 through 5. This is a rather puzzling chain. 4 of the galaxies show a redshift that puts them at about 700 million light-years with only a very small variation, smaller than normally found in such chains in fact. But then there's that oddball one. Can you spot it?
