Longo (Univ. Trieste and INFN Trieste), A. Giuliani (INAF/IASF-Mi), report on behalf of the AGILE Team: The AGILE satellite detected emission most likely associated with the long burst GRB 200808A reported by Fermi-GBM (GCN #28230). The event is visible in the scientific ratemeters of the SuperAGILE detector (SA; 18-60 keV), starting at T0 = 2020-08-08 11:15:05 (UT). The SA light curve shows two separate emission episodes about 250 s apart. The first episode lasted about 27 s and released ~4350 counts; the second episode lasted about 50 s and released ~7900 counts in the detector, above a background rate of 60 Hz. The event has an off-axis angle of about 40 degrees. The SA light curve can be found at: http://www.agilescienceapp.it/notices/GRB200808A_AGILE_RMs.png . No detection is visible in the scientific ratemeters of the MiniCALorimeter (MCAL; 0.4-100 MeV). Additional analysis of AGILE data is in progress.
