Object name: ARP233
Arp 233/UGC 5720/HARO 02 is a blue compact galaxy in Ursa Major about 75 million light-years distant. It is a starburst galaxy. NED classifies it as Im Pec with HII emission lines. Arp put it in his category Galaxies (not classifiable as S or E): Appearance of Fission, one of his largest categories. He made the comment: "Narrow faint absorption lane in south-following direction." This is likely the reddish band best seen on my enlarged cropped image on the southeast end of the brightest part of the galaxy. The HARO catalog lists blue galaxies with emission lines. It is also MRK 0033 which lists ultraviolet excess sources and SBS 1029+546, a catalog of emission line source. None of this was known when Arp made his atlas.
