report on behalf of the Insight-HXMT team:

At 2020-06-01T02:19:56.50 (T0), Insight-HXMT/HE detected 
GRB 200601A (trigger ID: HEB200601097) in a routine search of the data, 
which also triggered Fermi/GBM (GCN #27876).

The Insight-HXMT/HE light curve mainly consists of multiple 
pulses with a duration (T90) of 149.42 s measured from T0-2.12 s. 
The 1-ms peak rate, measured from T0-1.08 s, is 808 cnts/sec. 
The total counts from this burst is 29488 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).
