(IAA-CSIC, Granada), report on behalf of a larger collaboration:
"We have carried out I-band observations of the Swift GRB 100902A
(Sakamoto et al. GCNC 11181) on Sep 3.1076 - 3.1492 UT (~7.05 hr after
the onset of the burst, mean observing time) with the 1.5m telescope at
Observatorio de Sierra Nevada, Spain. We do not detect any optical
source within the SWIFT/XRT error circle (Beardmore et al. GCNC 11188).
The 3 sigma limiting magnitude of the co-added I-band image (Texp=16x200s)
is I ~ 21.8, calibrated against the USNO B1.0 catalogue."
