英文摘要	During the commissioning phase, at 2017-11-20T13:20:02.00 (T0),Insight-HXMT detected GRB 171120A (trigger ID: HEB171120555)in a routine search of the data, which was also observed bySwift/BAT (A. Tohuvavohu et al, GCN Circ.22133), Swift/XRT(P.A. Evans et al, GCN Circ.22135),Fermi/GBM(M.Stanbro et al, GCN Circ.22138),Fermi/LAT(F. Longo et al, GCN Circ.22136), Konus-Windan(D.Frederikset al, GCN Circ.22142) and AstroSat/CZTI (V.Sharma et al, GCN Circ.22143).The Insight-HXMT light curve consists of two pulses with a duration (T90)of 39.9s measured from T0+0.5s. The 200-ms peak rate, measured from T0+0.6s, is 6895.7 cnts/sec. The total counts from this burst is 5746.9 counts.URL_LC: http://www.hxmt.org/images/GRB/HEB171120555_lc.jpgAll measurements above are made with the CsI detectors operating in theregular mode with the energy range of about 80-800 keV (record energy).Only gamma-rays with energy greater than about 200 keV can penetratethe spacecraft and leave signals in the CsI detectors installed insideof the telescope.The time-averaged spectrum from T0-0.2 to T0+1.0 s is adequately fit by a Power Law model with spectral index = -1.96 +/- 0.07 . The energy fluenceis (6.20 +/- 0.33) E-06 erg/cm^2 in 200 - 5000 keV in this time interval.The analysis results presented above are preliminary; final results will be published elsewhere.Insight-HXMT is the first Chinese space X-ray telescope, which was fundedjointly by the China National Space Administration (CNSA) and the ChineseAcademy of Sciences (CAS).
