The AGILE satellite detected the long GRB 211105A at T0 = 2021-11-05
04:36:04 s (UTC).
The burst is clearly visible in the AGILE scientific ratemeters of the
SuperAGILE (SA; 20-60 keV) and MiniCALorimeter (MCAL; 0.4-100 MeV)
detectors. The event lasted about 100 s and it released a total number of
14900 counts in the SA detector (above a background rate of 105 Hz) and
133500 counts in the MCAL detector (above a background rate of 1240 Hz).

Additional analysis of AGILE data is in progress.
