Waratkar et al., GCN #45483).\n \nThe Insight-HXMT/HE light curve mainly consists of multiple pulses with a T90 of 9 +7/-3 s. The 1 s peak rate, measured from T0+5.5 s, is 552 cnts/sec. Insight-HXMT/HE detected a total of 3815 counts from this burst.\n \nThe Insight-HXMT/HE light curve can be found here:\nhttps://www.bursthub.cn/gcn/2026/hxmtgrb260830A.png\n \nAll measurements above are made with the CsI detectors of Insight-HXMT/HE operating in the Normal mode with the energy range of about 60-900 keV (deposited 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.\n \nInsight-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).
