report on behalf of the AGILE Team:

The AGILE satellite detected the GRB 220910A at T0 = 2022-09-10 05:48:26 s
(UTC). The burst is clearly visible in the AGILE scientific ratemeters of
the 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 8416 counts in the MCAL detector (above a background rate of 1310 Hz)
and 25992 counts in the AC detector (above a background rate of 4830 Hz).

Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert
