report on behalf of the AGILETeam:

The AGILE Mini-CALorimeter (MCAL) detected a burst at T0 = 2018-07-20
05:06:03.29 +/- 0.01 s (UTC), lasting about ~ 3.6 s in the 0.4-100 MeV
energy range. The light curve is composed of a single smooth peak and
released a total of ~3000 counts at E> 400 keV in the detector, above an
average background rate of 20 counts / 32 ms.

Further analysis is still in progress.

The AGILE-MCAL detector has a full solid angle acceptance, and is
operational in the range 0.4 - 100 MeV.
