reports:

A  short burst has been detected by IBAS in the  IBIS/ISGRI data at
17:14:50.7  UT of 2021 July 6. The burst was clearly localized at the
position of the galactic magnetar SGR 1935+2154 and a notice with the
source identification was distributed in real time (IBAS Alert Packet
n.9294).

The burst had a duration of about 50 ms.  A preliminary analysis indicates
a fluence of  about 1e-7  erg/cmq (20-200 keV).
