The burst signal was seen by all CGBM detectors.\n\nThe burst light curve shows a single multi-peaked pulse which starts\nat T=2.7 sec, peaks at 5.1 sec and ends at T+20.5 sec.\nThe precursor is not seen in the CGBM data.\nThe T90 and T50 durations measured by the SGM data are\n12.6 +- 2.3 sec and 4.5 +- 0.5 sec (40-1000 keV), respectively.\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1237502436/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
