on behalf of the AGILE Team:

The AGILE Mini-CALorimeter (MCAL) detected a short burst at T0 = 2021-02-05
14:46:09.14 +/- 0.01 s (UTC).

The event lasted about 0.10 s and released a total number of ~94 counts in
the detector (in the 0.4-100 MeV energy range), above an average background
rate of 516 Hz, corresponding to a peak significance of ~8 sigma.

The MCAL light curve shows a single peak and can be found at

The AGILE-MCAL detector is a CsI detector with a 4 pi FoV, sensitive in the
energy range 0.4-100 MeV. Additional analysis of AGILE data is in progress.
