Object name: ARP121
Arp 121 is a pair of interacting galaxies in Cetus. Redshift data indicates rather rapid orbital motion which makes a distance estimate a bit fuzzy. I'll just say it is likely between 235 and 250 million light-years distant. The western galaxy is MCG -01-03-051, a Sa pec galaxy. The eastern one is MCG -01-03-052. I find no classification. Looks like an elliptical to me. It appears MCG -01-03-051 has had the worst of the encounter. There's a faint spray of stars between the two. I'm not sure to which galaxy they belong, most likely MCG -01-03-051. Arp classed it under Elliptical and elliptical-like galaxies: close to and perturbing spirals. His comment seems to just reiterate this; "Elliptical galaxy warping spiral." He is letting his images do the speaking it appears. There is a puff of something off the north end of MCG -01-03-051. I can't tell for sure if it is part of the galaxy or a different one. If a different one it isn't in any catalog that I found. This pair also would seem to fit under Arp's "Wind Effects" category as well.
