GRB 200716C: Insight-HXMT/HE detection

At 2020-07-16T22:57:41.18 (T0), Insight-HXMT/HE detected GRB 200716C (trigger ID: HEB200716956) in a routine search of the data, which also triggered Fermi/GBM (Fermi GBM team, GCN #28123), Swift/BAT (Ukwatta et al., GCN #28124), Fermi-LAT (Ohno et al., GCN #28130) and CALET GBM (Torii et al., GCN #28139). The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 2.16 s measured from T0+0.19 s. The 1-ms peak rate, measured from T0+0.31 s, is 27488 cnts/sec. The total counts from this burst is 6590 counts.

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).
