Zhang (IHEP),\nreport on behalf of the Insight-HXMT team:\n\nAt 2019-10-09T07:08:56.77 (T0), Insight-HXMT/HE detected \nGRB 191009A (trigger ID: HEB191009297) in a routine search of the data, \nwhich was also triggered by Fermi/GBM (GCN #25985). \n\nThe Insight-HXMT/HE light curve mainly consists of a single  \npulse with a duration (T90) of 17.76 s measured from T0-1.56 s. \nThe 1-ms peak rate, measured from T0+7.40 s, is 495 cnts/sec. \nThe total counts from this burst is 1769 counts. \nURL_LC: http://www.hxmt.org/images/GRB/HEB191009297_lc.jpg \n\nAll measurements above are made with the CsI detectors operating in the \nregular mode with the energy range of about 80-800 keV (deposited energy). \nOnly gamma-rays with energy greater than about 200 keV can penetrate \nthe spacecraft and leave signals in the CsI detectors installed inside \nof the telescope. \n\nInsight-HXMT is the first Chinese space X-ray telescope, which was \nfunded jointly by the China National Space Administration (CNSA) and \nthe Chinese Academy of Sciences (CAS). \nMore information about it could be found at: \nhttp://www.hxmt.org.",
