DescriptionA clear night, but a full moon. I searched for Arp targets that would be as far from the moon as possible, and this was the first I came up with... The two nucleii came up almost immediately. The bulbous end next. Eventually the loop structure began to fill in. In reviewing this prior to submission to the AL, I found Arp's category unconvincing. There are no remarks to assist. While it's possible we're seeing "material emanating" it strikes me that material could equally-likely be merging. There is a highly distorted structure to the emanations, and it looks suspiciously like a low surface brightness barred-spiral galaxy getting compressed by (presumably) a much denser elliptical galaxy. Either way it's a "peculiar" galaxy in Arp's terms, but common sense suggests structured material is more likely to be coming in that out.
