Corwin's Notes

===== NGC 3855 may be IC 2953 and NGC 3856 may be NGC 3847. These were both found by d'A. Unfortunately, he provides only a crude position for the first; the second is mentioned only in his description, with not even an offset given. Dreyer concocted the position in the GC Supplement and the NGC from the scanty information that d'A has in his description of N3855. So, there have been several guesses made at the identities by Wolf, Spitaler, CGCG, and RNGC. I think they are all wrong, and that d'A probably saw IC 2953 and NGC 3847. These are the brightest galaxies in the area, so would be the ones most likely seen during a hurried observation. However, this too is a guess -- a better one, I think -- but still a guess.

Steve's Notes

===== NGC 3855 17.5" (4/14/01): faint, small, round, 0.8', low even surface brightness 17.5" (2/24/90): very faint, very small, round, low surface brightness. On a line with two mag 14 stars located 6'-7' SE. In a group with NGC 3847 10' NNW, IC 2952 1.8' W and MCG +06-26-028 4.5' ESE (not observed on 2/24/90). The identifications are very uncertain in this group.
