report on behalf of the AGILE Team:

The AGILE satellite detected the GRB 230402A at T0 = 2023-04-02 07:32:35 s
reported by Fermi GBM (GCN #33553).

The burst is clearly visible in the AGILE scientific ratemeters of the
MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence (AC; 50-200 keV)
The event lasted about 6 s and it released a total number of 5504 counts in
the MCAL
detector (above a background rate of 576 Hz), and 23987 counts in AC
(above a background rate of 2949 Hz). The AGILE ratemeters light curves can
be found
at .

At the T0, the event was 81 deg off-axis.

Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert
can be found at:
