The observation started at 12-09-07:42:13 UT, or about 0.5 hrs \nafter the BAT alert. H-band images were taken using a guider camera\nrevealing a bright NIR counterpart with its flux at H~12 mag.\nNote that calibration is done by an observation of a standard star \nnext night and needs a further refinement.\nNIR spectra were taken at 0.8-2.5 micron with R=750 for \nabout 24 min, starting at ~35 min after the BAT alert,\nshowing good S/N but no obvious features in raw spectra. \nAnalysis of the spectral/imaging data is onging.",
