Martin (PO-UWA)\nreport:\n\nWe imaged the field of GRB 130313A detected by SWIFT\n(trigger 550906) with the Zadko robotic telescope (D=100cm)\nlocated at the observatory - Gingin, Australia.\n\nThe observations started 52.3s after the GRB trigger\n(34.2s after the notice). The elevation of the field increased from\n19 degrees above horizon and weather conditions\nwere good.\n\nThe first image is trailed with a duration of 60.0s\n(see the description in Klotz et al., 2006, A&A 451, L39).\nWe do not detect any optical transcient with a limiting\nmagnitude of:\nt0+52.3s to t0+112.3s : R > 17.2\n\nThe second image is 30.0s exposure in tracking mode:\nt0+130s to t0+160s : R > 18.6\n\nWe co-added a series of exposures:\nt0+131s to t0+320.0s : R > 19.3\n\nMagnitudes were estimated with the nearby USNO-B1 stars\nand are not corrected for galactic dust extinction.\n\nThis message may be cited.",
