Kawai(Tokyo Tech) report on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 100915A (Littlejohns et al., GCN 11277)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the Murikabushi 1m telescope of Ishigakijima Astronomical\nObservatory.\n\nThe observation started on 10 10:46:01 UT (~9.2 h after the trigger).\nWe did not find any new point source within the enhanced XRT error\ncircle (Osborne et al., GCNC 11279) in all the three bands.\n\nThree sigma upper limits of the OT are listed below. We used GSC2.3\ncatalog for flux calibration.\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.40450    11:13:34   2760.0    >22.0  >21.5  >21.0\n0.56696    15:07:30   4560.0    >22.5  >21.8  >21.1\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
