report on behalf of the Insight-HXMT team:
At 2024-05-29T02:58:31.000 (T0), Insight-HXMT/HE detected
GRB 240529A(trigger ID: HEB240529123) in a routine search of the data,
which was also observed by Swift (Eyles-Ferris et al. GCN 36556; C. B. Markwardt et al. GCN 36566).
The Insight-HXMT/HE light curve consists of multiple
pulses with a duration (T90) of 66.23s measured from T0-37.26 s.
The 1s peak rate, measured from T0-0.159 s, is 3138 cnts/sec.
The total counts from this burst is 53027 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
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).
