P. O'Brien, E. Rol, N. Bannister (U. Leicester) report:


The 2-m Faulkes Telescope North robotically followed up GRB071003
(Schady et al., GCN Circ. 6837) beginning 189 s after the GRB
trigger time (UT 07:40:55).
We clearly detect the afterglow (Li et al., GCN Circ. 6838).
We measure the following magnitudes in the R filter:

Start Time from trigger
(s)                       Exp(s)      mag R
----------------------------------------------------
189                        10         14.72 +/- 0.01
210                        10         14.81 +/- 0.01
229                        10         14.90 +/- 0.01
----------------------------------------------------

Magnitudes are calibrated with respect to several nearby
USNO-B1 objects.
