Fletcher\n(University of Western Australia)\nM. Todd, M. Zadnik (Curtin University)\nM. Boer, A. Klotz (TAROT)\n\n\nOn 18 Nov, the Zadko Telescope team observed the XRT field of GRB  \n081118 reported by P. Evans (GCN 8525) using the 1 meter Zadko  \nTelescope (in very early commissioning mode). Imaging commenced  \napprox 1.96 hr post burst trigger using an unfiltered integrating CCD  \nvideo camera and continued over a period of 1 hr.\n  The OA candidate reported by GCN 8529 is seen in a selected stack  \nof 40 x 5 second exposures, though it is near the detection limit.\n  We do not have absolute standard star photometric calibration.\nUsing nearby USNO-B1 stars we estimate the limiting magnitude of the  \nOA to be in the range 20.9 +- 0.5.\n\nThis message is quotable in publications.\n\nDavid Coward and Timo Vaalsta report on behalf of the UWA Zadko  \nTelescope Team.",
