  "body": "Hao-Xuan Guo, Chen-Wei Wang, Cheng-Kui Li, Shao-Lin Xiong, and Chao Zheng (IHEP) report on behalf of the Insight-HXMT team:\n\nAt 2026-04-14T06:32:07.400 (T0), Insight-HXMT/HE detected a long burst, GRB 260414A, which is also detected by Fermi/GBM (Fermi GBM Team, GCN #44293) and Glowbug (C.C. Cheung et al., GCN #44297).\n\nThe Insight-HXMT/HE light curve mainly consists of multiple pulses with a total duration (T90) of 34.5 +7/-11 s. The 1s peak rate, measured from T0+0.25 s, is 818 cnts/sec. Insight-HXMT/HE detected a total of 6318 counts from this burst.\n\nThe Insight-HXMT /HE light curve can be found here:\nhttps://www.bursthub.cn//admin/static/hxmtgrb260414A.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).
