report on behalf of the Insight-HXMT team:
At 2020-10-13T03:46:30.200 (T0), Insight-HXMT/HE detected
GRB 201013A (trigger ID: HEB201013157) in a routine search of the data,
which also triggered Swift/BAT (Page K. L. et al., GCN #28607) and
CALET (Tamura T. et al., GCN #28618).
The Insight-HXMT/HE light curve mainly consists of multiple
pulses with a duration (T90) of 6.77 s measured from T0+0.23 s.
The 1-ms peak rate, measured from T0+0.53 s, is 20268 cnts/sec.
The total counts from this burst is 31971 counts.

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).
