A. Monfardini, C. Guidorzi, C.J. Mottram, C. Mundell (Liverpool John
Moores University) and the Liverpool GRB team, on behalf of the larger
Robonet consortium, report:
"We obtained late BVRI images of the SXC error box of GRB041211 (GCN 2839)
with the 2-m Faulkes Telescope North on Maui. New observations began on
December 15.549 UT (4.069 days after the GRB) under average seeing conditions.
We compared 3x120 sec. R filter exposures with an early 120 sec exposure
(GCN 2845). We found no significant variations or disappearances.
We thus conclude:
Time from GRB Time from GRB ExpTime Filter Limit Mag.
(days) (hours) (s)

0.140 3.36 120 R > 21.5
The probability of chance positional coincidence with a field star has
been estimated to be approximately 0.06.
The above limit magnitude has been derived using the calibration provided
by Henden et al. (GCN 2844)."
