Steve's Notes
=====
NGC 4911
18" (4/20/12): fairly faint, moderately large, oval NW-SE, 45"x35", broad concentration. A mag 14.5 star lies 52" SE. Forms a close pair with NGC 4911A = PGC 83751, just 36" SW of center. The companion was just visible as an extremely faint and small knot, ~12" diameter. NGC 4919 lies 4.9' NE. NGC 4911 is one of the two giant spirals in the Coma cluster.
17.5" (4/21/90): fairly faint, fairly small, oval WNW-ESE, weak concentration. A mag 12 star is 2' NW. Forms a close double with the very faint galaxy NGC 4911A at the southwest edge (not seen).
13" (5/14/83): faint, small, round. A mag 13 star is close west. First of three in the field. Located 18' SE of core of AGC 1656.
