V = 8.9;  Size 7

18" (6/25/04): at 300x, partially resolved into a couple of dozen stars, 
particularly on the south side of the very ragged 3' halo which surrounds the 
bright 50" core.  At 538x, perhaps 3 dozen stars are resolved mostly in the 
halo, but also several are superimposed on the very mottled core including one 
very close to the geometric center.  The halo is irregular, but clearly 
elongaged N-S with more extension resolution on the south side.  A number of 
extremely faint stars pop in and out of view with the seeing and the cluster 
seems of the verge of more extensive resolution.

17.5" (8/5/94): bright, 3.0' diameter, round.  Fairly sharp concentration with a 
1.5' diameter very bright core.  The halo has about two dozen stars peppered in 
the outer regions; the brightest star is on the NE side of the core.  The core 
is very lively and just starts to break up in to several very faint stars and a 
single obvious star.  A mag 9.5 star is just 2' W of center.

17.5" (7/9/94): bright, fairly small, 3.5' diameter, very bright core.  At 225x, 
20-25 stars are resolved in the halo mostly in the southern portion.  Contains 
an intense 1.5' core with a much fainter halo to 3.5' which extends almost to a 
mag 9.5 star 2' W of center.  The bright core itself is very lively and mottled 
with a few faint stars resolved and a single brighter star just E of the 
geometric center.

13": fairly bright, moderately large, bright core, small outer halo resolved 
into approximately 15 stars mainly south of the core, mottled.  A mag 9 star is 
2' W.

8": mottled, fainter halo, clumpy at 400x but no resolution.
