Corwin's Notes

===== NGC 4993 = NGC 4994. I do not know where JH's incorrect declination for this observation of N4994 came from, but it is 50 arcmin too far north (his father got the right position for the galaxy). Whatever happened, JH's observation fits exactly in RA and in its description of the galaxy, so I am confident of the identity. There is nothing at JH's position. LEDA has picked up a galaxy too faint and small for JH to have seen, and it is well off his position by non-digit amounts (21 seconds of time and 4.3 arcmin).

Steve's Notes

===== NGC 4993 17.5" (4/13/96): fairly faint, fairly small, round, 1.0' diameter. Pretty symmetrical appearance increasing to a 30" brighter core and a 10" nucleus. Located 5.3' WNW of mag 8.5 SAO 181423 and 20' SE of mag 5 Psi Hydrae.
