the AGILE Team:

The AGILE Mini-CALorimeter (MCAL) detected a burst at T0 = 2021-07-05
05:26:25.67 +/- 0.01 s (UTC).

The event lasted about 0.32 s and released a total number of ~300 counts in
the detector (in the 0.4-100 MeV energy range), above an average background
rate of 586 Hz. The MCAL light curve can be found at
http://www.agilescienceapp.it/notices/073779_GRB_MCAL_552547585.675289.png .

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.
