No real-time\nCGBM GCN notice was distributed about this trigger because\nthe real-time communication from the ISS was off (loss of signal).\n\nThe burst light curve shows a single pulse which starts\nat T-3.5 sec, peaks at T+4.5 sec and ends at T+11.6 sec.\nThe T90 and the T50 durations measured by the SGM data are\n12.0 +- 1.1 sec and 5.1 +- 0.5 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1213820487\n\nThe CALET data used in this analysis are provided by the Waseda CALET\nOperation Center located at the Waseda University.",
