The imager has effective aperture of 0.91 m.\n\nObservations started from 15:19 UT on 15th September, just 2 hours after\nthe BAT trigger, to 16:02 UT.  The total exposure of 35 min was\nsuccessfully obtained.\n\nIn our co-add image, we did not find any new point source within the\nenhanced XRT error circle (P.A. Evans et al., GCNC 12340) down to\nlimiting magnitude of  J=17.3 (Vega, S/N=3) . The photometric\ncalibration was made against 2MASS field stars.\n\nT0+[s]      MID-UT     T-EXP[sec]      J\n---------------------------------------------------\n +8130      15:35          2110       >17.3\n---------------------------------------------------\nT0+ : Elapsed time after the burt [sec]\nT-EXP: Total Exposure time [sec]",
