on behalf of the AGILE Team:

The AGILE satellite detected the long GRB 201207A at T0 = 2020-12-07
23:26:59 (UTC), reported by Fermi/GBM (GCN #28996) and AstroSat CZTI (GCN
#29000).

The burst is clearly visible in the AGILE scientific ratemeters of the
SuperAGILE (SA; 20-60 keV), MiniCALorimeter (MCAL; 0.4-100 MeV), and
AntiCoincidence (AC; 50-200 keV) detectors. The event lasted ~6 s and
released a total number of 640 counts in the SA detector (above a
background rate of 90 Hz), 8045 counts in the MCAL detector (above a
background rate of 1270 Hz), and 22670 counts in the AC detector (above a
background rate of 3630 Hz). The AGILE ratemeter light curves can be found
at http://www.agilescienceapp.it/notices/GRB_201207A_AGILE_RM.png .

The event also triggered a partial high time resolution MCAL data
acquisition.

Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert
