Marrocchesi (U of Siena)\nand the CALET collaboration:\n\nThe bright GRB 171216B (INTEGRAL SPI-ACS trigger #7972; Hurley et al.\nGCN circ. 22263) triggered the CALET Gamma-ray Burst Monitor (CGBM) at\n14:25:47.14 on 16 December 2017.  The burst signal was seen by the all instruments.\n\nThe light curve of the SGM shows several short peaks. The emission starts\nat T0, peaks at T+3 sec and ends at T+5 sec.  The T90 duration measured\nby the SGM data is 3.5 +- 0.4 sec (40-1000 keV).\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1197469387/\n\nThe CALET data used in this analysis are provided by the Waseda CALET Operation\nCenter located at the Waseda University.",
