Li (IHEP/THU),\nF. J. Lu, L. M. Song, H. Y. Wang, M. Wu, Y. P. Xu, S. N. Zhang (IHEP),\nreport on behalf of the Insight-HXMT team:\n\n\nDuring the commissioning phase, at 2017-09-04T09:46:00.62 (T0),\nInsight-HXMT detected GRB 170904A (trigger ID: HEB170904406)\nin a routine search of the data, which was also observed by\nINTEGRAL/SPI-ACS and Swift/BAT.\n\n\nThe Insight-HXMT light curve consists of multiple pulses\nwith a duration (T90) of 10.9 s measured from T0+0.1 s.\nThe 1-s peak rate, measured from T0+1.0 s, is 4655.1 cnts/sec.\nThe total counts from this burst is 43647.2 counts.\n\n\nURL_LC: http://www.hxmt.org/images/GRB/HEB170904406_lc.jpg\n\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\n\nThe analysis results presented above are preliminary;\nfinal results will be published elsewhere.\n\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).
