We did not find any new point source within the XRT\ncircle (Kocevski et al., GCNC 19478) in all the three bands.\n\nThree sigma upper limits of the OT are listed below.\nWe used SDSS-DR8 catalog for flux calibration.\n\n#T0+[day]  MID-UT    T-EXP[sec]   g'    Rc     Ic\n-----------------------------------------------------\n0.01716    15:07:45    2460.0   >20.5  >20.3  >19.3\n-----------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
