report on behalf of the Insight-HXMT team: 
 
At 2018-12-01T02:39:53.000 (T0), the Insight-HXMT/HE detected 
GRB 181201A (trigger ID: HEB181201111) in a routine search of the data, 
which was also triggered by INTEGRAL (S. Mereghetti et al.,GCN 23469);
Fermi/LAT (M. Arimoto et al., GCN23480).
 
The Insight-HXMT/HE light curve mainly consists of Single 
pulse with a duration (T90) of 15.18 s measured from T0+1.56 s. 
The 1-s peak rate, measured from T0+5.28 s, is 13844.5 cnts/s. 
The total counts from this burst is 88444.0 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).
