Arya et. al., GCN #44130) and Konus-Wind (IPN notice).\n\nThe Insight-HXMT/HE light curve mainly consists of two emission episodes with a total duration (T90) of 98 +14/-6 s. The 1s peak rate, measured from T0-1 s, is 2435 cnts/sec. Insight-HXMT/HE detected a total of 22378 counts from this burst.  \n\nThe Insight-HXMT /HE light curve can be found here: \nhttps://www.bursthub.cn//admin/static/hxmtgrb260327A.png  \n\nAll measurements above are made with the CsI detectors of Insight-HXMT/HE operating in the regular 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).
