The AGILE Mini-CALorimeter (MCAL) detected a short burst at
T0 = 2023-04-10 04:31:20.09 �� 0.01 s (UTC).
The event lasted 0.13 s and released a total number of 227 counts in the
MCAL detector (in the 0.4-100 MeV energy range), above a background rate
of 537 Hz. The MCAL light curve can be found at:
https://tools.ssdc.asi.it/ImgView/Agile/GRB230410B_083053_60818588008894555 
.

The burst is also clearly visible in the AGILE scientific ratemeters of
the MCAL detector (0.4-100 MeV), and marginally in that of the
AntiCoincidence (AC; 50-200 keV) detectors.

The event lasted about 1 s and it released a total number of 1690 counts
in the MCAL detector (above a background rate of 1109 Hz), 7078
counts in AC-Top detector (above a background rate of 3263 Hz), and
7271 counts in AC-Lat1 detector (above a background rate of 3171 Hz).

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