17.5" (10/13/90): fairly faint, very large, elongated almost 2:1 SSW-NNE, 5'x3', 
very low almost even surface brightness.  Contains a faint stellar nucleus or a 
mag 13.5 star is superimposed just N of center.  Gradually fades into 
background.  This is a satellite system of M31 and a Local Group member.

17.5" (8/29/92): appears larger (8'x4') using 20mm Nagler in White Mountains.

8": very faint, moderately large, slightly elongated, diffuse.
