The burst\nsignal was seen by the all CGBM instruments.\n\nThe light curve of the SGM shows two overlapping pulses.  The emission\nstarts at T+3 sec, peaks at T+4 sec and ends at T+16 sec.  The T90 and\nthe T50 durations measured by the SGM data are 11.3 +- 1.3 sec and\n7.0 +- 0.6 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1199846617\n\nThe CALET data used in this analysis are provided by the Waseda CALET Operation\nCenter located at the Waseda University.",
