the AGILE Team:

The AGILE satellite detected emission compatible with Fermi-GBM trigger No
624139481, at T0 = 2020-10-11 20:04:36 (UT). The event is visible in the
scientific ratemeters of the SuperAGILE detector (18-60 keV). The event
lasted about ~15 s and released 1670 counts in the detector (above a
background rate of ~84 Hz). The SuperAGILE RM light curve can be found at:
http://www.agilescienceapp.it/notices/529531476_AGILE_RMs.png .

We notice that the preliminary Fermi-GBM position of this event is
compatible, within the large error box, with the recently discovered SGR
1830-0645 (Page et al., GCN 28594; Krimm et al., 28599; Tohuvavohu et al,
GCN 28603).

Additional analysis of AGILE data is in progress.
