GRB 231123C: Insight-HXMT/HE detection
Abstract
At 2023-11-23T19:58:25.38 (T0), Insight-HXMT/HE detected GRB 231123C (trigger ID: HEB231123832) in a routine search of the data, which was also observed by Fermi/GBM (Fermi GBM Team, GCN 35171), Swift/BAT(James DeLaunay et al., GCN 35179) and Glowbug (C. C. Cheung et al., GCN 35184). The Insight-HXMT/HE light curve mainly consists of single pulse with a duration (T90) of 0.41 s measured from T0-0.24 s. The 1-ms peak rate, measured from T0-0.09 s, is 1741 cnts/sec. The total counts from this burst is 291 counts.

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).
