Corwin's Notes
=====
NGC 4869. Probably seen by JH and d'A; see NGC 4864 and NGC 4872. This was
certainly seen by Bigourdan, though there is a curiosity with his comparison
star. That star, called "Anon. c" by Bigourdan, is Tyc 1995-1839-1 and has a
relatively large proper motion: -99.4 milliarcseconds/year in RA and +46.7
mas/yr in Dec. If these are taken into account, Bigourdan's positions fall a
full second of time off the galaxy nuclei. If they are NOT taken into
account, Bigourdan's positions are very close to the nuclei. I suspect a bug
in my offset program. Working on it.

NGC 4869
18" (4/20/12): fairly faint, small, round, 20" diameter. A mag 14.4 star is attached at the NW edge. This Coma cluster member is situated 4' SW of NGC 4874, on a line with a mag 12.3 star that is 2' SW the center of NGC 4874.
17.5" (4/21/90): faint, small, round, weak concentration. A mag 14 star is attached at the NW edge 16" from the center and a mag 12 star is 2.0' NNE. Located in the core of AGC 1656 4.0' SW of NGC 4874 with a number of galaxies near including NGC 4875 3' ESE, IC 3973 3' SE and NGC 4872 3.2' NE.
13" (5/14/83): faint, small, round. A mag 13 star is attached at the NW edge. Located 5' SW NGC 4874 in AGC 1656.
