Object name: KKH042
kkh 42 also known as UGC 4129 is a double galaxy in northern Cepheus less than 4 degrees from the pole only 84 million light-years away by redshift. It's two components are MCG +14-04-044 and MCG +14-04-045. I find very little on this system. It appears the two are interacting but whether they will merge or not I don't know. The system, including the plumes, is only some 26,000 light-years across so they are dwarf systems. Is the blue color due to massive star formation due to their interaction or were they blue before that happened? Lots of questions but no answers that I could find. I don't even know how it came to my attention. I never noted that in my notes. It certainly would have fit any of several of Arp's categories yet it isn't on my Arp-like list. I can't understand why it wasn't there.
