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:
Trigger Time (UTC)
2022-01-20T18:52:48.950
2022-01-23T20:06:38.750
2022-01-24T02:10:55.050
2022-01-24T02:27:07.400
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).
