Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 110213A (D'Elia et al., GCNC 11705)\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 2011-02-13 09:45:46 UT (~4.5 hours after\nthe burst). We detected the previously reported afterglow\n(Cenko, GCNC 11706) in all the three bands.\n\n\nPhotometric results and are listed below. We used GSC2.3 catalog for\nflux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'  g'_err   Rc  Rc_err   Ic  Ic_err\n----------------------------------------------------------------------\n0.19696    10:01:06   1620.0    18.26  0.09  17.15  0.05  16.53  0.06\n0.21845    10:32:02   1620.0    18.78  0.11  17.51  0.05  16.75  0.05\n0.23993    11:02:59   1620.0    18.79  0.16  17.60  0.07  17.05  0.07\n----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
