Penacchioni, P. S. Marrocchesi (U of Siena)\nand the CALET collaboration:\n\nThe short GRB 180716A (Konus-Wind trigger time on 19:27:20.845 UT)\ntriggered the CALET Gamma-ray Burst Monitor (CGBM) at 19:27:24.372 UTC\non 16 July 2018. This GRB is also clearly seen by the publicly available\nINTEGRAL SPI-ACS light curve.\nNo real-time CGBM GCN notice was distributed about this trigger\nbecause the real-time communication from the ISS was off (loss of signal).\nThe burst signal was seen only by the SGM instrument.\n\nThe burst light curve shows a structured pulse which starts\nat T-0.38 sec, peaks at T-0.13 sec, and ends at T+0.26 sec.\nThere is a weaker pulse marginally seen at ~T-0.9 sec.\nThe T90 and the T50 durations measured by the SGM data are\n0.58 +- 0.18 sec and 0.26 +- 0.18 sec (40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1215804335/\n\nThe CALET data used in this analysis are provided by the Waseda CALET\nOperation Center located at the Waseda University.",
