Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 101024A (Krimm et al., GCN 11484)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the MITSuME 50cm telescope of Okayama Astrophysical Observatory.\n\nThe observation started on 2010-12-24 08:59:48 UT (~3.6 hours after\nthe burst). We did not find any new point source within the\nUVOT-enhanced XRT error circle (Page et al., GCNC 11485) in all\nthe three bands.\n\nThree sigma upper limits of the OT are listed below. We used\nGSC2.3 catalog for flux calibration.\n\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.18147    09:47:32  4680.0     >19.9  >19.7  >18.9\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
