The AGILE satellite detected a short burst at T0 = 2022-01-12 08:39:25
(UTC), compatible with the fourth bright burst from the SGR1935+2154
recently reported by GECAM (GCN #31443).

The event is clearly visible in the AGILE scientific ratemeters of the
SuperAGILE (SA; 20-60 keV) and AntiCoincidence (AC; 50-200 keV) detectors.
The burst released a total number of 117 counts in the SA detector (above a
background rate of 100 Hz), and 4938 counts in the AC detector (above a
background rate of 3575 Hz). The AGILE ratemeter light curves can be found
at http://www.agilescienceapp.it/notices/SGR220112_AGILE_RM.png .

Additional analysis of AGILE data is in progress.
