Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 120212A (Sonbas et al., GCNC 12230)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the Murikabushi 1m telescope of Ishigakijima Astronomical\nObservatory.\n\nThe observation started on 2012-02-12 12:27:12 UT (~3.3 h after the burst).\nWe detected the previously reported afterglow (Guidorzi et al.,GCNC 12932;\nKawabata et al., GCNC 12935; Yanagisawa et al., GCNC 12936) in Rc and Ic\nbands.\n\nPhotometric results of the OT are listed below. We used GSC2.3 catalog\nfor flux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'    Rc  Rc_err   Ic  Ic_err\n----------------------------------------------------------------------\n0.14653    12:42:22    780.0    >20.2  18.7 0.2     18.4 0.3\n----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
