  "body": "Xue-Yuan Zao, Zheng-Hang Yu, Cheng-Kui Li, Shao-Lin Xiong, and Chao Zheng report on behalf of the Insight-HXMT team:\n\nAt 2025-10-02T20:14:52.800 (T0), Insight-HXMT/HE detected a long burst GRB 251002A, which is also detected by Fermi/GBM (Jacob Smith et al., GCN #42093) and SVOM/ECLAIRs (A. Saccardi et al., GCN #42060). \n\nThe Insight-HXMT/HE light curve mainly consists of multiple pulses with a T90 of 13.8 +2.3/-3.1 s. The 1s peak rate, measured from T0+6.050 s, is 1080 cnts/sec. The total counts from this burst is 4528 counts. \n \nThe HXMT/HE light curve can be found here: \nhttps://www.bursthub.cn//admin/static/hxmtgrb251002A.png \n\nAll measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 30-1000 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).
