report on behalf of the AGILE Team:
The AGILE satellite detected the GRB 221126A at T0 = 2022-11-26 13:07:29 s
(UTC), reported by Fermi/GBM (GCN #32985), Swift/BAT (GCN #32987) and
AstroSat CZTI (GCN #32990).
The burst is clearly visible in the AGILE scientific ratemeters of the
AntiCoincidence, (AC-Top; 50-200 keV) detector. The event lasted about 6 s
and it released a total number of 25792 counts in the AC-Top detector
(above a background rate of 3388 Hz). The AGILE ratemeters light curves
can be found at http://www.agilescienceapp.it/notices/GRB221126A.png.
At the T0, the event was 51.82 deg off-axis.
Additional analysis of AGILE data is in progress. Automatic MCAL GRB alert
