The burst signal was seen by only the SGM detector.\n\nThe burst light curve shows a multi-peaked pulse which starts at T+0.1 sec,\npeaks at T+1.6 sec and ends at T+4.6 sec. The T90 and T50 durations\nmeasured by the SGM data are 4.0 +- 0.7 sec and 2.1 +- 0.9 sec (40-1000\nkeV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1266191565/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
