and INFN Trieste), report on behalf of the AGILE Team:

The AGILE mini-calorimeter (MCAL) detected a short hard burst at T0 =
2020-01-28 12:23:29.98 +/- 0.01 s (UTC).

The event triggered the 64 ms MCAL logic timescale and lasted about 0.10 s,
releasing a total number of ~90 counts in the detector (in the 0.4-100 MeV
energy range), above an average background rate of ~500 counts / s.

The 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.
