report on behalf of GECAM team:

GECAM-B has detected a series of bursts very probably from SGR J1935+2154,
either by in-flight trigger or by on-ground search of the data.
Here is the list of these bursts:

Locations of all these bursts are consistent with SGR J1935+2154.

Please note that all GECAM results here are preliminary. The final analysis
will be published in journal papers or GECAM online catalog.

Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor
(GECAM) mission consists of two small satellites (GECAM-A and GECAM-B) in
Low Earth Orbit (600 km, 29 deg), launched on Dec 10, 2020 (Beijing Time),
which was funded by the Chinese Academy of Sciences (CAS).
