Steve's Notes

===== NGC 1003 18" (12/18/06): fairly bright, fairly large, elongated 3:1 ~E-W, 2.5'x0.9', broad concentration with a large, brighter core. The core brightens slightly to the center but there is no distinct nucleus, although the center has a mottled appearance with an occasional sparkle or two (possibly a faint, superimposed star or a slightly brighter knot). A mag 13 star is just off the NE edge of the core. Located 2' NE mag 10 SAO 38196 and two degrees SSW of M34. Member of the NGC 1023 Group. 17.5" (11/1/86): moderately bright, elongated 3:1 WNW-ESE, bright core. A mag 13 star is involved at the NE side, just 0.8' from center. Located 2' NE of a mag 10 star. 13" (12/22/84): moderately bright, elongated ~E-W, weak concentration. A mag 13 star is on the NE edge 0.8' from center. An extremely faint knot is at the NW edge.
