Description:
Andrew's Murrell's log of Van den Bergh-Hagen 176 is the only
other observation I've seen of this globular. Here is mine from
my decidedly poorer northern hemisphere Texas location. The gc
was just 10o above the horizon when I observed it at culmination.
Seen at a very low altitude so this globular cluster was difficult,
using MegaStar chart and replotted location from William Harris'
database of Milky Way Globulars. I saw 5 (13-14th magnitude) stars
with a faint background glow about 4' in size. This cluster appears
visually more like an open cluster than a globular in the eyepiece.
The professional literature reinstated this object as a probable
gc in 1995. (ortolani, Bica, and Barbuy 1995, A&A 300, 726.)
