The burst signal was seen by all CGBM detectors.\n\nThe burst light curve shows a single pulse which starts at T+0 sec,\npeaks at T+0.19 sec and ends at T+0.45 sec. The T90 and T50 durations\nmeasured by the SGM data are 0.38 +- 0.14 sec and\n0.19 +- 0.06 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1241929925/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
