Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 100802A (Troja et al., GCNC 11031)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the MITSuME 50cm telescope of Okayama Astrophysical Observatory.\nThe observation started on 2010-08-02 11:43:26 UT (~6 h after\nthe burst). We did not find any new point source within the XRT\nerror circle and the enhanced XRT error circle (Evans et al.,\nGCNC 11036) in all the three bands. Also, we could not detect the\npreviously reported afterglow (Siegel and Troya, GCN 11032).\n\nThree sigma upper limits of the OT are listed below. We used\nGSC 2.3 catalog for flux calibration.\n\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.29658    12:52:41  9480.0     >19.9  >19.8  >19.3\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
