Modern observations

Brian Skiff

POSS: pa75. no brtr area SE or SW, unless this is -70 (25cm). m13.5 * is at

2'.0 in pa65, gx points just barely S of it. core sharply def on S

flank, core sl NE of geom center.

UGC: pa68.

NGC: pa84.

Lick: pa75.

15cm - much lgr and obviously velong compared to -69. 140x: pa70, points S of

m13.5 * NE. length sl longer than distance to this *. halo seems asym:

more rounded on NE end, tapered on SW; flattened on S-facing flank (twd

-70). core vthin, offset sl twd NE end from center; has *ings along it.

BS, 6Sep1989, Anderson Mesa.

25cm - nrly as br as -69. elong NE-SW. broad core w/cen bright band. brtr area

SW. 1'.2x0'.7 overall.

30cm - easy, comparable in brtness to -69. elong pa45. ENE 2' is m12 *. obj SW

1'.1 is -70? (yes)
