Giuliani (INAF/IASF-Mi), report on behalf of the AGILE Team: The AGILE satellite detected the GRB 220511A at T0 = 2022-05-11 13:41:57 (UTC), reported by Fermi GBM (GCN #32018). The burst is clearly visible in the AGILE scientific ratemeters of the SuperAGILE (SA; 20-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV) detectors. The event lasted about 3 s and it released a total number of 410 counts in the SA detector (above a background rate of 70 Hz), 5150 counts in the MCAL detector (above a background rate of 1230 Hz), and 15270 counts in the AC detector (above a background rate of 3500 Hz).
