Jens Hjorth and Jose Maria Castro Ceron (DARK, NBI) report:

Using ALFOSC on the 2.56-meter Nordic Optical Telescope,
we have obtained a 300 s R-band image of the GRB 050922C
field (Swift trigger: 156467, GCN#4013 (Norris et al.)).
Using a preliminary photometric zeropoint we estimate the
following magnitude for the afterglow:

R ~ 16.5 @ 1 hour post-burst.

The coordinates are:
(RA, Dec)(J2000.0) = (21:09:33.083, -08:45:30.2)
with a 0.2" error in each coordiante.

A finding chart of the field is available at:
