Sorry to have missed most of the M31 Glob-fu. I have been out in
Washington DC and just flew back tonight to find the TAC threads.
I observed both G312 and 318 on a great night up at Fremont Peak on
January 6th of this year.
G312 was at the very limit with the 14.5 inch scope Starmaster. It
could be seen with averted vision about 10% of the time when seeing
would steady. I sketched its position with respect to faint stars and
confirmed that what I was seeing was in exactly the right place as
shown on the Hodge atlas (pages 34 and 35).
G318 was easier, visible with averted vision approximately 50% of
the time, and making the apex of a slightly squashed equilateral
triangle together with two brighter field stars to south.
The relative difficulty of seeing G 312 and G318 was consistent with
their visual magnitudes as given by Barmby (V 16.13 and 15.33,
respectively) http://cfa-www.harvard.edu/~pbarmby/m31gc/table1.txt.
Both globs appeared completely stellar, which is typical for all but
the brightest globs in M31.

I agree with Peter and Leonard that the glob in the Hubble shot
appears to be G312.
Amazing how much other stuff can be seen in the Hubble field.
