Zhang (IHEP), report on behalf of the \nInsight-HXMT team:\n\nAt 2018-01-11T16:42:06 (T0), Insight-HXMT/HE detected \nGRB 180111A (trigger ID: HEB180111695) in a routine search of the \ndata,which is also triggered by Swift/BAT (Lien et al.,GCN \n22318),AGILE/MCAL(Verrecchia et al.,GCN 22321),and CALET(Asaoka et \nal.,GCN 22333).\n\nThe Insight-HXMT/HE light curve mainly consists of \nmulti-pulses with a duration (T90) of 19.94 s measured from T0+0.185 s. \nThe 500-ms peak rate, measured from T0+0.422 s, is 2332.29 cnts/sec.\nThe total counts from this burst is 13972.02 counts. URL_LC: \nhttp://www.hxmt.org/images/GRB/HEB180111695_lc.jpg\n\nAll measurements above are made with the CsI detectors operating in the GRB mode, in \nwhich the energy range is increased to about 200 - 3000 keV (record \nenergy), compared to the normal mode of 80 - 800 keV. Only gamma-rays \nwith energy greater than about 200 keV can penetrate the spacecraft and \nleave signals in the CsI detectors installed inside of the telescope. \n\nThe analysis results presented above are preliminary; final results will \nbe published elsewhere. Insight-HXMT is the first Chinese space X-ray \ntelescope, which was funded jointly by the China National Space \nAdministration (CNSA) and the Chinese Academy of Sciences (CAS).
