Zhang, F. Zhang, J. Zhang,\nT. Zhang, S. N. Zhang (IHEP), report on behalf of the Insight-HXMT team:\n\nDuring the commissioning phase, at 2017-06-26T09:37:22.32 (T0),\nInsight-HXMT detected GRB 170626A (trigger ID: HEB170626400)\nin a routine search of the data, which was also observed by the Swift/BAT\n(Marshall et al. 2017, GCN 21264) and the Fermi/GBM\n(Hamburg et al. 2017, GCN 21266).\n\nThe Insight-HXMT light curve mainly consists of several pulses\nwith a duration (T90) of 12.1 s measured from T0-0.43 s.\nThe 1-second peak rate, measured from T0+0.5 s, is 3275.0 cnts/sec.\nThe total counts from this burst is 9887 counts.\nAll measurements above are made with the CsI detectors in the energy range\nof about 80-840 keV. Please note that this is the deposited energy,\nrather than the incident photon energy.\n\nURL_LC: http://www.hxmt.org/images/GRB/HEB170626400_lc.jpg\n\nThe time-averaged spectrum from T0-2.5s to T0+12.5 s is\nadequately fit by a Power Law model with spectral index = -1.85 +/- 0.03.\nThe event fluence (200 -50000 keV) in this time interval is\n(1.86 +/- 0.09)E-05 erg/cm^2.\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\nthe Chinese Academy of Sciences (CAS).\nMore information about this telescope could be found at:\nhttp://www.hxmt.org/index.php/enhome .",
