The AGILE satellite detected the long GRB 210517A at T0 = 2021-05-17
05:28:01 s (UTC), reported by Swift (GCNs #30032, #30034).
The burst is visible in the AGILE scientific ratemeters of the SuperAGILE
(SA; 20-60 keV) and MiniCALorimeter (MCAL; 0.4-100 MeV) detectors. The
event lasted ~6 s and released a total number of 663 counts in the SA
detector (above a background rate of 77 Hz) and 8759 counts in the MCAL
detector (above a background rate of 1200 Hz). The AGILE ratemeter light
curves can be found at

Additional analysis of AGILE data is in progress.
