TITLE: GCN CIRCULAR NUMBER: 14213 SUBJECT: GRB 130215A: TAROT La Silla observatory optical observations DATE: 13/02/15 11:08:54 GMT FROM: Bruce Gendre at ASDC Gendre B. (Artemis/IRAP), Dereli, H. (Artemis/OCA), Atteia J.L. (IRAP-CNRS-OMP), Boer M. (UNS-CNRS-OCA), Klotz A. (IRAP-CNRS-OMP) report: We imaged the field of GRB 130215A detected by SWIFT (trigger 548760, D'Elia et al., GCN 14204) with the TAROT robotic telescope located at the European Southern Observatory, La Silla observatory, Chile. The observations started 15.5s after the GCN notice (704.3s after the SWIFT trigger). The elevation of the field decreased from 20 degrees above horizon and weather conditions were good. At the position reported by Zheng et al. (GCN 14205) we clearly detect the afterglow between 704s and 5481 seconds after the trigger. We also confirm the peak in the light curve around 750s post-trigger announced by Zheng et al. (GCN 14208). We obtained the following magnitudes, calibrated with three different USNO-B1 objects (statistical 3 sigma errors are of the order of 0.1-0.2), and not corrected for galactic extinction. MidTime (s) R mag 719 13.8 1192 14.4 1795 15.0 2723 15.7 4439 16.3 N.B. Galactic coordinates are lon=163.0747 lat=-39.7685 and the galactic extinction in R band is 0.3 magnitudes estimated from D. Schlegel et al. 1998ApJ...500..525S. This message may be cited.
