Giuliani (INAF/IASF-Mi), report on behalf of the AGILE Team: The AGILE satellite detected the long GRB 200716A reported by Fermi-GBM (GCN #28109, trigger 616555602.759372 / 200716060), occurring at T0 = 2020-07-16 01:26:37 s (UTC). The event is clearly visible in the scientific ratemeters (RMs) of the SuperAGILE (SA, 18-60 keV), MiniCALorimeter (MCAL, 0.4-100 MeV), and Anti-Coincidence (50-200 keV) detectors. Their light curves show a multi-peaked profile, lasting about ~60 s and releasing ~4200 counts in the SA detector (above a background rate of 60 Hz), ~75200 counts in the MCAL detector (above a background rate of 1200 Hz), and ~225000 counts in the AC detector (above a background rate of 3700 Hz). The AGILE RMs light curves can be found at http://www.agilescienceapp.it/notices/GRB200716A_AGILE_RMs.png . The intense episode occurring at about T0 + 30 s triggered a MCAL high time resolution data acquisition. The time-integrated spectrum of this episode in ~7 s can be fitted in the energy range 0.4-10 MeV with a single power-law with ph.ind. = 1.51 -0.05/+0.05, resulting in a reduced chi-squared of 1.6 (48 d.o.f.). The episode fluence in the same energy range and time interval is 3.5e-05 ergs/cm^2 (90% confidence level). Additional analysis of AGILE data is in progress.
