GCN Circular 11822
D. Suzuki (STE Lab. Nagoya Univ.), P.J. Tristram (Mt. John University Observatory), S. Kobara, K. Omori, H. Naito and T. Sako (STE Lab. Nagoya Univ.) on behalf of the MOA Collaboration report : We searched for an optical afterglow of GRB110318B (GCN 11799, R. Margutti et al.) starting from 15:40 UT on 2011 March 18 (13 minutes after the burst) with the MOA-II 1.8m telescope at Mt.John observatory in New Zealand. In a single image of a 60 sec exposure with a wideband Red filter (center wavelength ~ 750nm and FWHM ~ 250nm), we did not find any object within the error circle of the Swift XRT source position (GCN 11803, P.A. Evans et al.). A 3 sigma upper limit is set in the I magnitude at 20.7 mag. This photometry was done by using the DoPhot and calibrated against the USNO-B1.0 catalog stars, and not corrected for the Galactic extinction.
