Steve's Notes

===== NGC 4240 18" (5/28/06): fairly faint, small, round, 25" diameter. Contains a very small bright core ~10" diameter which increases to a bright substellar nucleus. Located just east of a mag 13 star (24" from the center). 18" (3/13/04): faint, small, round, 30" diameter, strongly concentrated with a very small bright core and stellar nucleus. A mag 13 star is barely off the west edge. Observation made through thin clouds.
