TITLE: GCN CIRCULAR NUMBER: 16059 SUBJECT: GRB 140323A: Zadko observatory - Gingin optical observations DATE: 14/03/31 17:47:35 GMT FROM: Alain Klotz at IRAP-CNRS-OMP A. Klotz, D. Turpin (IRAP-CNRS-OMP), D. Macpherson (UWA/ICRAR), D. Coward (UWA), M. Boer, B. Gendre, K. Siellez, H. Dereli, O. Bardho (UNS-CNRS-OCA), A. Williams (PO-UWA), R. Martin (PO-UWA) report: We imaged the field of GRB 140323A detected by SWIFT (trigger 592916) with the Zadko robotic telescope (D=100cm) located at the observatory - Gingin, Australia. The observations started 1.0 hour after the GRB trigger. The elevation of the field was at 27 degrees above horizon and weather conditions were good. We co-added a series of exposures. We do not detect any optical candidate in the XRT error box provided by Troja et al. (GCNC 16027) at the limiting magnitude of: From t0+1.0h to t0+1.6h Rlim=20.8 Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction. N.B. Galactic coordinates are lon=306.3802 lat=-36.7801
