TITLE: GCN CIRCULAR NUMBER: 6848 SUBJECT: GRB071003: Faulkes Telescope North observations DATE: 07/10/04 10:15:37 GMT FROM: Cristiano Guidorzi at INAF-OAB C. Guidorzi (U. Bicocca & INAF-OAB), D.F. Bersier, R.J. Smith, C.J. Mottram, M.F. Bode, D. Carter, S. Kobayashi, A. Melandri, C.G. Mundell, I.A. Steele (Liverpool JMU), A. Gomboc (U. Ljubljana), P. O'Brien, E. Rol, N. Bannister (U. Leicester) report: The 2-m Faulkes Telescope North robotically followed up GRB071003 (Schady et al., GCN Circ. 6837) beginning 189 s after the GRB trigger time (UT 07:40:55). We clearly detect the afterglow (Li et al., GCN Circ. 6838). We measure the following magnitudes in the R filter: Start Time from trigger (s) Exp(s) mag R ---------------------------------------------------- 189 10 14.72 +/- 0.01 210 10 14.81 +/- 0.01 229 10 14.90 +/- 0.01 ---------------------------------------------------- Magnitudes are calibrated with respect to several nearby USNO-B1 objects.
