Corwin's Notes
=====
NGC 4004 = NGC 4004A. The secondary designation comes from Holmberg's 1937
monograph and catalogue of multiple galaxies. He always called the brightest
galaxy of a multiplet "a", the second "b", and so on. In this case, "NGC
4004B" is IC 2982 (which see).
Steve's Notes
=====
NGC 4004
17.5" (4/9/99): fairly faint, fairly small, very elongated 3:1 SSW-NNE, 1.2'x0.4', no concentration. A mag 13.5 star is close following [57" SE of center]. Last and brightest of a trio with IC 2982 3.1' W and NGC 3988. IC 2982 appeared faint, very small, elongated 20"x15" SW-NE. Just follows a mag 11 star [45" to center] which is the brightest star in an inverted "L" asterism and which detracts from viewing.
On the DSS, NGC 4004 appears to be an interacting, distorted galaxy (or the result) with a long tidal tail to the south.
