Marrocchesi (U of Siena)\nand the CALET collaboration:\n\nThe long-duration GRB 170514A (Bissaldi et al., GCN Circ. 21094;\nKonus-Wind trigger time on 04:18:42.056 UT) triggered the CALET\nGamma-ray Burst Monitor (CGBM) at 04:19:59.08 on 14 May 2017.\nThe burst signal was seen by all CGBM instruments.  Because of a\nproblem in one of the ground alert processing script, the GCN notice\nwas not distributed automatically for this event.  Note that the CGBM\ntriggered at the 2nd bright burst episode which was ~1 min after the\ninitial peak.\n\nThe light curve of the SGM shows two separated peaks.  The initial peak,\nwhich triggered Fermi-GBM and Konus-Wind, shows the emission around T-70 sec.\nThe 2nd peak starts from T-1 sec, peaks at T+0 sec and ends at T+10 sec.\nThe T90 duration measured by the SGM data is 7.8 +- 0.6 sec (40-1000 keV).\n\nThe light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/flight/1178770293/\n\nThe CALET data used in this analysis are provided by the Waseda\nCALET Operation Center located at the Waseda University.",
