Gompertz et al., GCNC 15071) with the \noptical three color (g', Rc, and Ic) CCD cameras attached to the MITSuME 50 cm\ntelescope of Akeno Observatory, Yamanashi, Japan.\n\nThe observation started on 2013-08-06 14:11:23 UT ( ~11.3 h afterthe burst).\nAnd we could not find any new point source within the XRT\nerror circle (A.P. Beardmore et al., GCNC 15072) in all the three bands.\n\nThe results of photometry (3 sigma upper limits) are listed below.\nWe used GSC2.3 catalog for flux calibration.\n\n\nT0+[hour]      MID-UT        T-EXP[sec]           g'                Rc                Ic\n----------------------------------------------------------------------------------------------------\n   ~15.0         17:50:01          5580               >21.3         >20.4           >19.7\n----------------------------------------------------------------------------------------------------\nT0+ : Elapsed time after the burst [hour]\nT-EXP: Total Exposure time [sec]",
