英文摘要	Insight-HXMT was taking data normally around the trigger time(T0=2019-05-03 17:23:08 UTC) of this high-energy neutrino event (GCN 24381), which was monitored without any occultation by the Earth. Within T0 ± 100 s, no significant excess events (SNR > 3 sigma) are found in a search of the Insight-HXMT/HE raw light curves.Assuming the counterpart GRB with three typical GRB Band spectral models, two typical duration timescales(1 s, 10 s) coming from the position of this neutrion event, the 5-sigma upper-limits fluence (0.2 - 5 MeV, incident energy)are reported below:Band model 1 (alpha=-1.9, beta=-3.7, Ep=70 keV):1s: 1.8e-07 erg cm^-2 10s: 6.1e-07 erg cm^-2 Band model 2 (alpha=-1.0, beta=-2.3, Ep=230 keV):1s: 2.7e-07 erg cm^-2 10s: 9.7e-07 erg cm^-2Band model 3 (alpha=-0.0, beta=-1.5, Ep=1000 keV):1s: 4.6e-07 erg cm^-2 10s: 2.2e-06 erg cm^-2 Further analysis will be reported in the following circulars.All 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.Insight-HXMT is the first Chinese space X-ray telescope, which was fundedjointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
