Arp 38 (NGC 6412, UGC 10897 and others) is a nice spiral located approximately 74 million light-years away in Draco. In the ‘Spiral galaxies – companions on arms – low surface brightness companions’ class, it looks like Arp might have made a mistake. There doesn’t appear to be any companions. I have a feeling some of the knots in NGC 6412 were thought to be galaxies.
