[vsnet-alert 14812] Re: PNV J09410000-5759540

[Rob Kaufman]

Animation of the field on 28 July 12 & earlier shot on 27 May linked here,
limiting magnitude around 12.5:

To get mag 10.3 unf per earlier report, I used the 9.92 star used by Josch
and V-mag 10.51 star NOMAD 0319-0169903 (Tycho-2 8593-00003-1), magnitudes
from Vizier.  These are the two small stars showing close to and top-right
of the PNV in the animation.  As I said, it's very rough using only one
sub, maybe skies will be better tonight.  DSS coloured plate sourced in
Aladin shows a little cluster of stars very close to the reported position,
the brightest at V-mag 13.3.
