on behalf of the AGILE Team:

The AGILE satellite detected GRB 210207B, reported by Swift (GCNs #29420,
#29422, #29427) and Konus-Wind (GCN #29426) at T0 = 2021-02-07 21:52:08
(UT).

The AGILE Mini-CALorimeter (MCAL; 0.4-100 MeV) scientific ratemeters
clearly detected the main peak of the burst, which occurred at T0 + 40 s,
as reported by Swift/BAT. The episode lasted ~4 s and released 7950 counts
in the MCAL detector, above a background rate of 1250 Hz. The AGILE
ratemeters light curve can be found at:

was 160�� off-axis.

Additional analysis of AGILE data is in progress.
