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.
