D. Bersier, C. Guidorzi, Z. Cano, S. Kobayashi report on behalf of a
larger collaboration:
We observed the location of GRB100725A (GCN 10979) with the Faulkes
Telescope South,
starting at the beginning of the night (1.7 hour after trigger). In a 5
minutes R-band
exposure, we do not detect any source not present on the DSS inside the
enhanced XRT error
circle (GCN 10980). Any source at m=20.0 would have been clearly
detected. The same holds
for a 6x5minutes exposure at a magnitude m=21.3.
