Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 110201A (D'Elia et al., GCN 11699)\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 2011-02-12 11:11:56 UT (~10 hours\nafter the burst). We did not find any new point source within the\nBAT refined error circle (Ukwatta et al., GCNC 11703) in all the\nthree 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------------------------------------------------------\n0.46043    12:12:08  5880.0     >20.0  >19.7  >19.0\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
