Arp 200 was not conspicuous despite being listed at 12th magnitude. It lies at one end of a curve of faint stars running E then turning N. Initially it appeared as a coarsely mottled circular patch with an offset core and a knot of brightness near the adjacent star. Later it appeared as a blocky oval, with suggestions of structure, lighter and darker striations, running NW-SE, like a dab by an artist’s brush.
