Omori (STE Lab, Nagoya Univ.)\non behalf of the MOA Collaboration  report:\n\nWe searched for an optical afterglow of GRB 100625A (GCN 10884, S. T. Holland et al.)\nstarting from 18:49 UT on 2010 June 25th (17 minutes after the BAT trigger)\nwith the MOA-II 1.8m telescope at Mt.John observatory in New Zealand.\nIn a single image of a 60sec exposure with a wide-band 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 10884).\nA 3 sigma upper limit is set in the I magnitude at 22.77 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.",
