Object name: ARP323
Designation(s): ARP323, HCG98,
Arp 323 is part of Hickson 98 or maybe the entire group, sources vary. In any case, it is a galaxy group in western Pisces about 345 million light years. The bright pair is NGC 7783. Some catalogs show them as 7783 and 7783A while others say 7783A and 7783B or like NED NGC 7783 NED 01 and NGC 7783 NED 02. All left to right. In the MCG catalog, they are MCG +0-60-58 and MCG +0-60-59. Though the Kanipe-Webb book shows the western one as 7783 and the eastern as MCG +0-69-59. All very confusing. In the Hickson catalog, they are 98A and 98B respectively. The galaxy to the north is MCG +0-60-60 or Hickson 98D with the southern one below a field star being NGC 7783C or Hickson 98C. I'll use Hickson letters as they are something most agree on.
