Kawai(Tokyo Tech)\nreport on behalf of MITSuME and OISTER collaboration:\n\nWe observed the field of GRB 160225A (Siegel et al., GCNC 19075)\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 2016-02-25 14:26:51 UT (~5.9 min after\nthe burst). We detected the previously reported afterglow (Yoshii\net al., GCNC 19080) in Rc and Ic bands.\n\nPhotometric results and three sigma upper limit of the OT are\nlisted below. We used SDSS-DR7 catalog for flux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'    Rc  Rc_err  Ic  Ic_err\n------------------------------------------------------------------\n0.00777    14:32:08     540.0   >19.4   18.6 0.2    17.8 0.2\n------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
