Marrocchesi (U of Siena) and the CALET collaboration:\n\nThe long-duration GRB 160720A (Hamburg, et al., GCN circ. 19724;\nHurley, et al., GCN circ. 19726; Svinkin, et al. GCN circ. 19727;\nAmelushkin, et al. GCN circ. 19728) triggered the CALET Gamma-ray\nBurst Monitor (CGBM) at 18:25:16.38 on 20 July 2016.  No real time CGBM\nGCN notice was distributed about this trigger because the real time\ncommunication from the ISS was off (loss of signal) between 17:57 and\n18:45.  The burst signal was seen by all CGBM instruments.\n\nThe light curve of the SGM shows two main peaks.  The emission starts at\nT-5 sec and ends at T+30 sec.  The peak times of the main pulses are T+3 sec\nand T+10 sec.  The 3rd weak peak is visible at T+18 sec.  The T90 duration\nmeasured by the SGM data is 36.4 +- 1.7 sec (40-1000 keV).\n\nThe light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/flight/1153074224/\n\nThe CALET data used in this analysis are provided by the Waseda\nCALET Operation Center located at the Waseda University.",
