We could not detect the previously reported afterglow\n(Malesani et al., GCNC 20146; Butler et al., GCNC 20149)\nin all the three bands.\n\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-----------------------------------------------------\n0.63016    18:39:58    5940.0   >19.9  >19.6  >19.2\n-----------------------------------------------------\nT0+ : Elapsed time after the burst [day]\nT-EXP: Total Exposure time [sec]",
