Sako (STE Lab., Nagoya Univ.)\non behalf of the MOA Collaboration report:\n\nWe searched for an optical afterglow of GRB100704A (GCN 10929, D. Grupe et al.)\nstarting from 06:59:33 UT on 2010 July 4 (204 minutes after the burst)\nwith the MOA-II 1.8m telescope at Mt. John observatory in New Zealand.\nIn a single image of a 180 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 10930, J.P. Osborne et al.).\nA 3 sigma upper limit is set in the I magnitude at 22.0 mag.\n\nThis photometry was done by using the DoPHOT and calibrated against the\nUSNO-B1.0 catalog stars, and not corrected for the Galactic extinction.",
