Corwin's Notes

===== NGC 7204 is a peculiar interacting system. JH has only one observation of it, and notes it as pretty bright, large, and little extended. He notes no irregularity for it, so we have no idea which of the two main parts he saw. We will just have to assume that the whole assemblage is his object. See NGC 7202 for more about the triplet to which this belongs.

Steve's Notes

===== NGC 7204 24" (8/16/12): this strongly interacting double system appeared fairly faint, moderately large, elongated 3:2 E-W, irregular, ~1.0'x0.7'. At 280x it resolved into two galaxies. According to my notes the northwest component (MCG -05-52-008 = NGC 7204A) is more prominent with a higher surface brightness. The fainter galaxy is attached on the south side (MCG -05-52-009/NGC 7204B) and is elongated E-W, extending to the east, with the two glows barely resolved. 18" (10/25/08): this interacting double system is the furthest NNE is an equally spaced trio with NGC 7203 6.9' SSW and NGC 7201 13.5' SSW. At 174x it appeared faint, fairly small, elongated 2:1 E-W, fairly low surface brightness with no concentration. At 283x, it appeared brighter on the western side (due to the small companion galaxy just off the NW end), but the duo was not cleanly resolved. 17.5" (7/22/87): faint, fairly small, round, diffuse. Faintest and last of three with NGC 7201 13.5' SSW and NGC 7203 7.0' SSW. Mag 8.2 SAO 213556 is 7.2' NNE and mag 9.6 SAO 213549 5.8' N. This is an interacting double system but was not resolved.
