TITLE: GCN CIRCULAR NUMBER: 11183 SUBJECT: GRB 100902A: Faulkes Telescope South observations DATE: 10/09/02 20:28:11 GMT FROM: Cristiano Guidorzi at Ferrara U,Italy C. Guidorzi (U. Ferrara), A. Melandri (INAF-OAB), N. Tanvir (U. Leicester) on behalf of a large collaboration report: The 2-m Faulkes Telescope South automatically began observing GRB 100902A (Sakamoto et al. GCN Circ. 11181) on September 02, 19:34:38 UT, 164 seconds from the GRB trigger time and during the major gamma-ray spikes (GCN 11181). Within the XRT error circle we do not find any source down to the following limiting magnitudes: Mid time from Exposure Filter Limiting Magnitude trigger (s) (s) ------------------------------------------------------------ 169 10 R > 15.6 203 3x10 R > 16.0 ------------------------------------------------------------ Calibration is against some nearby USNOB-1 stars. The relatively poor limits are due to the vicinity to the Moon.
