Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 110530A (D'Avanzo et al., GCNC 12046)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the MITSuME 50cm telescope of Okayama Astrophysical Observatory.\nThe observation started on 2011-05-30 15:41:32 UT (~11 min after\nthe burst). We detected the previously reported afterglow\n(Yatsu et al., GCNC 12048) in Rc and Ic bands.\n\n\nPhotometric results and are listed below. We used GSC2.3 catalog for\nflux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'    Rc  Rc_err   Ic  Ic_err\n----------------------------------------------------------------------\n0.06460    17:04:03    5520.0   >20.3  19.8   0.2   19.6   0.2\n----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
