Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 111123A (Siegel et al., GCNC 12650)\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 2011-12-10 17:54:08 UT (~3.3 h after\nthe burst). We did not find any new point source within the enhanced\nXRT circle (Goad, et al., GCNC 12652) in all the three bands.\n\n\nThree sigma upper limits of the OT are listed below. We used\nSDSS catalog for flux calibration.\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.17952    18:55:34    5640.0    >18.9  >19.3  >18.9\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
