Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 110102A (Oates et al., GCN 11509)\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 2011-01-02 20:08:45 UT (~1.3 hours after\nthe burst).  We detected the afterglow candidate within the\nenhanced XRT error circle (Goad et al., GCNC 11510) in all the three\nbands.\n\nPhotometric results are listed below. We used SDSS catalog for flux\ncalibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'  g'_err   Rc  Rc_err   Ic  Ic_err\n----------------------------------------------------------------------\n0.06851    20:31:04  2340.0      20.0  0.4    19.6  0.3    18.3  0.2\n----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
