Zhang (IHEP),\nreport on behalf of the Insight-HXMT team:\n \nAt 2018-02-10T12:24:38.55 UT, the Insight-HXMT/HE detected\nGRB 180210A(trigger ID: HEB180210517) in a routine search of the data,\nwhich was also triggered by Fermi/GBM(GCN Circ. 22407),Fermi/LAT(GCN Circ. 22408), \nSwift/XRT(GCN Circ. 22413) and KONUS-Wind(GCN Circ. 22415).\n \nThe Insight-HXMT/HE light curve consists of a multi-peaked pulse\nwith a duration (T90) of 26.7 s measured from T0+3.9 s.\nThe 1-s peak rate, measured from T0+23.9 s, is 3173.8 cnts/sec.\nThe total counts from this burst is 40447.9 counts.\n\nURL_LC: http://www.hxmt.org/images/GRB/HEB180210517_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 (record 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\nThe time-averaged spectrum from T0-8 to T0+30 s is adequately fit by a Power\nLaw model with spectral index = -1.86 +/- 0.03. The energy fluence is \n(4.5 +/- 0.2) E-05 erg/cm^2 in 200 - 5000 keV in this time interval.\n \nThe analysis results presented above are preliminary, \nfinal results will be published elsewhere.\n \nInsight-HXMT is the first Chinese space X-ray telescope, which was funded\njointly by the China National Space Administration (CNSA) and the Chinese\nAcademy of Sciences (CAS).
