TITLE: GCN CIRCULAR NUMBER: 10208 SUBJECT: GRB 091127: TAROT La Silla observatory optical observations DATE: 09/11/29 16:48:23 GMT FROM: Alain Klotz at CESR-CNRS Klotz A. (CESR-OMP), Gendre B. (IASF), Boer M. (OHP-OAMP), Atteia J.L. (LATT-OMP) report: We imaged the field of GRB 091127 detected by Swift (trigger 377179) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile. We performed images between 1.12 and 1.37 day after the trigger using a R filter. We do not see the OT after co-addition of all images. The limiting magnitude is R=20.0.
