TITLE: GCN CIRCULAR NUMBER: 11656 SUBJECT: GRB 110206A: TAROT La Silla observatory optical observations DATE: 11/02/07 07:51:16 GMT FROM: Alain Klotz at CESR-CNRS Klotz A. (CESR-OMP), Gendre B. (ASDC), Lass-Bourez M. (UWA) Boer M. (OHP-OAMP), Atteia J.L. (LATT-OMP) report: We imaged the field of GRB 110206A detected by INTEGRAL (trigger 6088, Mereghetti et al. 2011 GCNC 11654) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile. The observations started 6.3h after the GRB trigger (beginning of the night). The elevation of the field increased from 57 degrees above horizon and weather conditions were good. We co-added a series of exposures t0+6.3h to t0+7.3h : R > 19.3 Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction. N.B. Galactic coordinates are lon=267.5629 lat=-28.2892 and the galactic extinction in R band is 0.1 magnitude estimated from D. Schlegel et al. 1998ApJ...500..525S. This message may be cited.
