report on behalf of the Insight-HXMT team:
At 2021-12-23T02:40:35.450 (T0), Insight-HXMT/HE detected
GRB 211223A (trigger ID: HEB211223111) in a routine search of the data,
which also triggered GECAM (GECAM Team, GCN #31286) and CALET.

All measurements above are made with the CsI detectors operating in the
regular mode with the energy range of about 80-800 keV (deposited energy).
Only gamma-rays with energy greater than about 200 keV can penetrate
the spacecraft and leave signals in the CsI detectors installed inside
of the telescope.
Insight-HXMT is the first Chinese space X-ray telescope, which was
funded jointly by the China National Space Administration (CNSA) and
the Chinese Academy of Sciences (CAS).
