Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 111215A (Oates et al., GCNC 12681)\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 2011-12-15 14:10:37 UT (~6.5 min after\nthe burst). We did not find any new point source within the enhanced\nXRT circle (Beardmore et al., GCNC 12690) in all the three bands.\n\nPhotometric results and are listed below. We used GSC2.3 catalog for\nflux calibration.\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.03242    14:50:49    3420.0    >18.6  >19.0  >18.7\n--------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
