GRB 191227A: Insight-HXMT/HE observation
Abstract
At 2019-12-27T01:39:34.400 (T0), Insight-HXMT/HE detected GRB 191227A (trigger ID: HEB191227069) in a routine search of the data, which was also triggered by Fermi/GBM, Swift/BAT and Konus-Wind (GCN #26593). The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 20.65 s measured from T0+0.40 s. The 1-ms peak rate, measured from T0+6.72 s, is 18,542 cnts/sec. The total counts from this burst is 118,722 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).
