Martin (PO-UWA)\nreport:\n\nWe imaged the field of the trigger 748858 detected by SWIFT\nwith the Zadko robotic telescope (D=100cm)\nlocated at the observatory - Gingin, Australia.\n\nThe observations started 4.25h after the GRB trigger.\nThe elevation of the field increased from\n18 degrees above horizon and weather conditions\nwere good.\n\nWe co-added a two series of exposures:\nt0+4.25h to t0+4.40h : Rlim = 20.1\nt0+4.65h to t0+5.22h : Rlim = 20.3\n\nNo source exhibit a variation flux compatible with\na GRB afterglow. All sources detected by Zadko are\npresents in the DR9 SDSS-III image.\n\nMagnitudes were estimated with the nearby NOMAD1 stars\nand are not corrected for galactic dust extinction.",
