The burst signal was seen by all CGBM detectors.\nBecause of a problem in one of the ground alert processing script, the GCN\nnotice was not distributed automatically for this event.\n\nThe burst light curve shows a multi-peaked structure which\nstarts at T-206 sec, peaks at T-3 sec and ends at T+221 sec.\nThe T90 and T50 durations measured by the SGM data are 347 +- 46 sec\nand 104 +- 29 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1263124124/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
