report on behalf of the Insight-HXMT team:
At 2018-12-12T16:37:45.500 (T0), the Insight-HXMT/HE detected
GRB 181212A (trigger ID: HEB181212692) in a routine search of the data,
which was also triggered by Fermi/GBM (Fletcher et al., GCN23524) and
Konus-Wind (Frederiks et al., GCN23540).
The Insight-HXMT/HE light curve mainly consists of single
pulse with a duration (T90) of 5.48 s measured from T0+0.72 s.
The 1-s peak rate, measured from T0+2.07 s, is 8019.2 cnts/s.
The total counts from this burst is 20371.7 counts.

All measurements above are made with the CsI detectors operating in the
regular mode with the energy range of about 80-800 keV (record 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
fundedjointly by the China National Space Administration (CNSA) and
the Chinese Academy of Sciences (CAS).
