Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 120327A (Sbarufatti et al., GCNC 13123)\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 2012-03-28 17:27:54 UT (~1.61 days after the\nburst). We could not detect the previously reported afterglow\n(Klotz et al., GCNC 13124; Smith et al., GCNC 13125; Kuroda et al.,\nGCNC 13156) in all the three bands.\n\nThree sigma upper limits of the OT are listed below. We used GSC2.3\ncatalog for flux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'     Rc    Ic\n----------------------------------------------------------------------\n1.62756    17:58:57   1500.0    >20.5  >20.2  >19.0\n----------------------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
