report on behalf of GECAM team:
Since the first report of a bright burst from SGR 1935+2154 (Y. Huang et
al.,
GCN 29363), GECAM has detected a series of bursts probably from this source,
either from in-flight trigger or from ground search of the data.
Here is the list of these bursts:
TrigTime(UTC)
2021-01-27T06:50:20.750
2021-01-29T14:17:25.000
2021-01-29T17:51:00.850
2021-01-30T08:39:53.850
2021-01-30T09:46:01.050
2021-01-30T17:40:54.800
Locations of all these bursts are consistent with SGR 1935+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).
