GCN Circ. 20974) triggered\nthe CALET Gamma-ray Burst Monitor (CGBM) at 22:27:27.91 on 30 March 2017.\nThe burst signal was seen by all CGBM instruments.\n\nThe light curve of the SGM shows several peaks.  The bright burst episode\nstarts at T-5 sec and ends at T+20 sec.  Two late time emissions at T+120 s\nand T+150 s, which triggered Swift/BAT, are barely visible in the HXM data.\nThe T90 duration measured by the SGM data is 18.5 +- 2.4 sec (40-1000 keV).\n\nThe light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/flight/1174947694/\n\nThe CALET data used in this analysis are provided by the Waseda\nCALET Operation Center located at the Waseda University.",
