report on behalf of a large collaboration:

On 2010 April 13 at 17:37:19 UT the 2-m Faulkes Telescope South
automatically began observing the Swift GRB 100413A
(Holland et al., GCN Circ. 10581) using the BVR, i' filters,
corresponding to 231 s after the burst trigger time.

Inside the XRT error circle (Goad et al. GCN Circ. 10584)
we do not detect any source at the following limiting
magnitudes:

Mid time from    Total Exp   Filter    Magnitude
trigger (min)    (s)
------------------------------------------------
04.52            3x10        R         > 19.8
28.6              540        R         > 22.2
33.2              520        i         > 21.3
------------------------------------------------

Magnitudes have been calibrated from nearby USNOB-1
stars, using the R2 and I magnitudes.
