GCN Circular 13094
Klotz A. (IRAP-CNRS-OMP), Gendre B. (ASDC/INAF-OAR), Boer M. (UNS-CNRS-OCA), Atteia J.L. (IRAP-CNRS-OMP) report: We imaged the field of GRB 120324A detected by SWIFT (trigger 518507) with the TAROT robotic telescope (D=25cm) located at the European Southern Observatory, La Silla observatory, Chile. The observations started 1.98h after the GRB trigger (it was not risen when the GRB occured). The elevation of the field increased from 11 degrees above horizon and weather conditions were good. We co-added a long series of exposures. We do not detect any OT in the XRT enhanced position (Evans et al. GCNC 13093): start end magnitude tgrb+1.98h tgrb+3.23h R > 19.7 Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction. N.B. Galactic coordinates are lon= 58.0588 lat= +4.0337 and the galactic extinction in R band is about 3 magnitudes estimated from D. Schlegel et al. 1998ApJ...500..525S. This message may be cited.
