The burst signal was seen by the HXM2 and SGM \ndetectors.\n\nThe burst light curve shows a weak pulse which starts at T-2.2 sec and\nends at T+4.8 sec. The T90 and T50 durations measured by the SGM data\nare 6.0 +- 2.2 sec and 3.0 +- 2.2 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1232801614/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
