of the AGILE Team:

The AGILE satellite detected the long GRB 210702A at T0 = 2021-07-02
19:07:13 s (UTC), reported by Swift (GCNs #30351, #30352, #30356, #30358)
and CALET (#30362).

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 about ~32 s
and it released a total number of 1630 counts in the SA detector (above a
background rate of 50 Hz), 40500 counts in the MCAL detector (above a
background rate of 1440 Hz), and 74310 counts in the AC detector (above a
background rate of 3610 Hz). The AGILE ratemeter light curves can be found
at http://www.agilescienceapp.it/notices/GRB210702A_AGILE_RM.png . The
event also triggered a partial high time resolution MCAL data acquisition.

Additional analysis of AGILE data is in progress.
