TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5633 SUBJECT: GRB060927: Faulkes Telescope South observation DATE: 06/09/27 15:55:29 GMT FROM: Cristiano Guidorzi at INAF-OAB C. Guidorzi (Univ Bicocca & INAF-OAB), D. Bersier (Liverpool JMU), A. Melandri, A. Gomboc (University of Ljubljana), I.A. Steele, R.J. Smith, C.G. Mundell, A. Monfardini, D. Carter, S. Kobayashi, M. Bode (Liverpool JMU), P. O'Brien, E. Rol, N. Bannister (Leicester) report: The 2m Faulkes Telescope South (Siding Spring, Australia) automatically reacted to the Swift burst GRB 060927 (trigger 231362, Barbier et al., GCN Circ. 5627) and began observing 1.78 minutes after the burst trigger time. We find an uncatalogued source in a 220s i'-band stacked image from 5.42 min to 20.35 min after the trigger time, lying 6.4" away from the XRT centroid and 1.7" away from the ROTSE-III candidate (Schaefer et al., GCN Circ. 5629): RA(J2000) = 21:58:12.0 Dec(J2000)= +05:21:49 We estimate i'=18.0 +- 0.5 and from a 390s R-band image we derive R>18. This source lies 6.4" from the APM galaxy mentioned by Barbier et al. (GCN Circ. 5627). Further observations are going on. This message can be cited.
