Trois (INAF/OA-Cagliari), I. Donnarumma (ASI), A. Giuliani (INAF/IASF-Mi), report 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: http://www.agilescienceapp.it/notices/GRB210207B_AGILE_RM.png . The event was 160° off-axis. Additional analysis of AGILE data is in progress.
