Kawai(Tokyo Tech)\nreport on behalf of MITSuME and OISTER collaboration:\n\nWe observed the field of GRB 161217A (D'Elia et al., GCNC 20276)\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 2016-12-17 12:40:15 UT (~11.2 h after\nthe burst). We did not find any new point source within the\nEnhanced XRT circle (Osborne et al., GCNC 20278) in all the three\nbands.\n\nThree sigma upper limits of the OT are listed below.\nWe used SDSS-DR8 catalog for flux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'    Rc     Ic\n-----------------------------------------------------\n0.51298    13:46:16    5760.0   >19.1  >19.1  >18.4\n0.76490    19:49:01    6180.0   >20.1  >19.9  >19.1\n-----------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]"
