The burst signal was seen only by the SGM instrument.\n\nThe light curve of the SGM shows a single peak.  The emission starts\nat T+3 sec, peaks at T+4.5 sec and ends at T+8 sec.  The T90 duration\nmeasured by the SGM data is 3.9 +- 0.4 sec (40-1000 keV).\n\nThe light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/flight/1180825585/\n\nThe CALET data used in this analysis are provided by the Waseda\nCALET Operation Center located at the Waseda University.",
