Kawai(Tokyo Tech)\nreport on behalf of the MITSuME collaboration:\n\nWe observed the field of GRB 120819A (Beardmore et al., GCNC 13681)\nwith the optical three color (g', Rc and Ic) CCD camera attached\nto the Murikabushi 1m telescope of Ishigakijima Astronomical Observatory.\n\nThe observation started on 2012-08-19 13:13:11 UT, (~3.0 min after the burst)\nWe did not find any new point source within the enhanced XRT circle\n(Beardmore et al., GCNC 13681) in all the three bands.\nWe also could not detect the previously reported afterglow (Malesani et al.,\nGCNC 13683).\n\n\nThree sigma upper limits of the OT are listed below. We used\nGSC2.3 catalog for flux calibration.\n\nT0+[day]   MID-UT   T-EXP[sec]    g'     Rc     Ic\n------------------------------------------------------\n0.01544    13:32:28    1980.0   >21.5  >21.6  >20.3\n------------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]"
