Zhang (THU), T. P. Li (IHEP/THU), F. J. Lu, L. M. Song, M. Wu, Y. P. Xu, S. N. Zhang (IHEP), report on behalf of the Insight-HXMT team: At 2021-01-19T02:54:09.82 (T0), Insight-HXMT/HE detected GRB 210119A (trigger ID: HEB210119120) in a routine search of the data, which was also triggered by Fermi/GBM (GCN #29322) and Swift/BAT (M. J. Moss. et al., GCN #29323). The Insight-HXMT/HE light curve mainly consists of a single   pulse with a duration (T90) of 0.03 s measured from T0+0.01 s. The 1-ms peak rate, measured from T0+0.004 s, is 4418 cnts/sec. The total counts from this burst is 62 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).
