Nagoya Univ.)\non behalf of the MOA Collaboration report :\n\nWe searched for an optical afterglow of GRB110318B (GCN 11799, R. Margutti\net al.)\nstarting from 15:40 UT on 2011 March 18 (13 minutes after the burst)\nwith the MOA-II 1.8m telescope at Mt.John observatory in New Zealand.\nIn a single image of a 60 sec exposure with a wideband Red filter (center\nwavelength ~ 750nm and FWHM ~ 250nm), we did not find any object\nwithin the error circle of the Swift XRT source position (GCN 11803, P.A.\nEvans et al.).\nA 3 sigma upper limit is set in the I magnitude at 20.7 mag.\n\nThis photometry was done by using the DoPhot and calibrated against\nthe USNO-B1.0 catalog stars, and not corrected for the Galactic extinction.",
