Mundell  \n(LJMU) report on behalf of a large collaboration:\n\nTha Faulkes Telescope South robotically observed the field of GRB  \n130803A starting ~ 2.9 minutes after the Swift trigger (Page et al.,  \nGCN 15059). We find no credible afterglow candidate in the XRT error  \ncircle.\n\nWe estimate a 3 sigma upper limit of R>20.0 (texp=30s) ~3.5 minutes  \nand I>21.9 (texp=700s) ~40 minutes after the burst.\n\nMagnitudes are calibrated against nearby USNOB-1 stars.",
