| Description | This is a truly obscure galaxy. Other than Arp, as far as I can tell, it's listed only as UGC 12265, which is the Upsala Catalog published in 1973. These are all northern hemisphere galaxies, mostly discovered at the Palomar observatory, which was Arp's home base. Arp 46 is actually the smaller (and lower) of the two galaxies you see in the image, the other being UBC 12267. I assume the "low surface brightness companion on arms" is the small bright spot (with galaxy-like halo) to the upper right (next to another bright circle, which appears to be a star within the milky way). |
