Marrocchesi (U of Siena) and the CALET collaboration:\n\nThe long-duration GRB 160721A (Fermi-GBM trigger #490821662;\nINTEGRAL-ACS trigger #7516) triggered the CALET Gamma-ray Burst\nMonitor (CGBM) at 19:20:58.54 on 21 July 2016.  The burst signal was\nseen by all CGBM instruments.\n\nThe light curve of the SGM shows two short spikes with a broad emission.\nThe short spikes are peaked at T+0 sec and T+1.8 sec with the durations\nless than a second.  The underline broad emission ends around T+10 sec.\nThe T90 duration measured by the SGM data is 8.6 +- 0.6 sec (40-1000 keV).\n\nThe light curve is available at\n\nhttp://cgbm.calet.jp/cgbm_trigger/flight/1153163965/\n\nThe CALET data used in this analysis are provided by the Waseda\nCALET Operation Center located at the Waseda University.",
