GRB 200227A: Insight-HXMT/HE detection
Abstract
At 2020-02-27T07:20:16.15 (T0), Insight-HXMT/HE detected GRB 200227A (trigger ID: HEB200227305) in a routine search of the data, which was also detected by Fermi/GBM (GCN #27233) and Swift-BAT (GCN #27234). The Insight-HXMT/HE light curve mainly consists of two pulses with a duration (T90) of 37.71 s measured from T0-6.92 s. The 1-ms peak rate, measured from T0+1.169 s, is 1862 cnts/sec. The total counts from this burst is 19259 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).
