the AGILE Team:

The AGILE satellite detected GRB 210112A, reported by Swift (GCNs #29289,
#29290), at T0 = 2021-01-12 01:37:58 (UT).

The event is clearly visible in the scientific ratemeters of the SuperAGILE
(SA; 18-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and AntiCoincidence
(AC; 50-200 keV) detectors. The burst lasted about 25 s and released 1120
counts in the SA detector (above a background rate of 60 Hz), 25140 counts
in the MCAL detector (above a background rate of 1250 Hz), and 71500 counts
in the AC detector (above a background rate of 3570 Hz). The AGILE
ratemeters light curves can be found at:

Additional analysis of AGILE data is in progress.
