Marrocchesi (U of Siena)\nand the CALET collaboration:\n\nThe long-duration GRB 170402A (Fermi GBM trigger #512808659;\nKonus-Wind trigger time on 06:50:51.076) triggered the CALET\nGamma-ray Burst Monitor (CGBM) at 06:50:52.11 on 2 April 2017.\nThe burst signal was only seen by the SGM instrument.\n\nThe light curve of the SGM shows several peaks.  The entire\nburst episode starts at T+2 sec and ends at T+12 sec.  Two bright\nemissions peak at T+3 sec and T+5 sec.  The T90 duration measured\nby the SGM data is 7.5 +- 0.6 sec (40-1000 keV).\n\nThe light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/flight/1175150695/\n\nThe CALET data used in this analysis are provided by the Waseda\nCALET Operation Center located at the Waseda University.",
