Marrocchesi (U of Siena),\nand the CALET collaboration:\n\nThe bright GRB 200716C (Swift detection: Ukwatta et al., GCN Circ. 28124,\nBarthelmy et al., GCN Circ. 28136; Fermi-LAT detection: Ohno et al.,\nGCN Circ. 28130; Fermi GBM detection: Veres and Meegan, GCN Circ. 28135;\nhttps://gcn.gsfc.nasa.gov/other/200716C.gcn3) triggered the CALET\nGamma-ray Burst Monitor (CGBM) at 22:57:41.346 UTC on 16 July 2020.\nThe burst signal was seen by all CGBM detectors.\nBecause of a problem in one of the ground alert processing script,\nthe GCN notice was not distributed automatically for this event.\n\nThe burst light curve shows two narrow pulses followed by a weak tail. The\nemission starts at T-0.1 sec and ends at T+6.8 sec. The T90 and T50\ndurations measured by the SGM data are 5.3 +- 1.1 sec and 1.9 +- 0.1 sec\n(40-1000 keV), respectively.\n\nThe ground processed light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/ground/1278975378/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at the Waseda University.",
