17.5" (7/10/99): This fairly bright globular is ~3.5' in diameter and sharply 
concentrated with a prominent 1.5' core.  The core appears slightly elongated N-
S, although the halo is circular or slightly elongated WSW-ENE.  At 220x the 
globular appears lively and mottled but there is no obvious resolution.  At 280x 
and especially 380x, the edge of the halo is very ragged and the surface is 
extensively mottled.  Around the periphery some threshold stars pop in and out 
of view particularly on the south side.

13": bright core surrounded by a round, even glow.  No resolution evident.
