The burst signal was seen by all CGBM detectors.\n\nThe burst light curve shows a multi-peaked structure which starts at\nT=1.9 sec, peaks at 6.0 sec and ends at T+27.4 sec.\nThe T90 and T50 durations measured by the SGM data are 15.5 +- 3.5 sec\nand 6.8 +- 0.6 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1240723364/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
