AbstractAt 2018-12-25T11:44:10.000 (T0), the Insight-HXMT/HE detected GRB 181225A (trigger ID: HEB181225489) in a routine search of the data, which was also triggered by by AGILE/MCAL (A. Ursi et al.,GCN23560)、Fermi/LAT (M. Arimoto et al., GCN23561) and Fermi/GBM (S.Poolakkil., GCN23562).The Insight-HXMT/HE light curve mainly consists of multiple pulses with a duration (T90) of 1.23 s measured from T0+0.46 s. The 50-ms peak rate, measured from T0+1.208 s, is 2963.2 cnts/s. The total counts from this burst 2350.8 counts. URL_LC: http://www.hxmt.org/images/GRB/HEB181225489_lc.jpg All measurements above are made with the CsI detectors operating in the GRB mode with the energy range of about 200-3000 keV (record energy). 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 fundedjointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
