  "body": "Xing-Hao Luo, Chen-Wei Wang, Chao Zheng, and Shao-Lin Xiong (IHEP) report on behalf of the Insight-HXMT team:\n\nAt 2026-07-10T12:56:43.800 (T0), Insight-HXMT/HE detected the GRB 260710A, which is also detected by Fermi/GBM (Fermi GBM Team, GCN #45131).\n\t\nThe Insight-HXMT/HE light curve mainly consists of a single pulse with a T90 of 1.2 +1.2/-0.4 s. The 1s peak rate, measured from T0-0.3 s, is 727 cnts/sec. Insight-HXMT/HE detected a total of 841 counts from this burst.\n\nThe HXMT/HE light curve can be found here:\nhttps://www.bursthub.cn/gcn/2026/hxmtgrb260710A.png\n\nAll measurements above are made with the CsI detectors of Insight-HXMT/HE operating in the regular mode with the energy range of about 60-900 keV (deposited energy). Only gamma-rays with energy greater than about 200 keV can penetrate the spacecraft and leave signals in the CsI detectors installed inside of the telescope.\n\nInsight-HXMT is the first Chinese space X-ray telescope, which was funded jointly by the China National Space Administration (CNSA) and the Chinese Academy of Sciences (CAS).
