Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 120711B (Page et al., GCNC 13431)\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 2012-07-11 14:35:55 UT (~11.4 h after the burst).\nWe did not find any new point source within the XRT error\ncircle (Page et al., GCNC 13431) in all the three bands.\n\nThree sigma upper limits 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     Ic\n----------------------------------------------------------------------\n0.49154    14:58:51   4200.0    >22.1   >21.7  >20.5\n----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
