The camera has an effective aperture\nof 0.91m.\n\nObservations started from 17:59 UT on 10th December, 3.37 hours after\nthe BAT trigger, to 19:35 UT.  The total exposure of 73 min was\nsuccessfully obtained.\n\nIn our co-add image, we did not find any new point source within the\nenhanced XRT error circle (Goad et al., GCNC 12652) down to limiting\nmagnitude of  J=16.0 (Vega, S/N=10). The photometric calibration was\nmade against 2MASS field stars.\n\nT0+[s]      MID-UT     T-EXP[sec]      J\n---------------------------------------------------\n +15,000   18:47          4,380       >16.0(S/N=10)\n---------------------------------------------------\nT0+ : Elapsed time after the burst [sec]\nT-EXP: Total Exposure time [sec]",
