  "body": "Chen-Wei Wang, Zheng-Hang Yu, Shao-Lin Xiong, Cheng-Kui Li, and Chao Zheng report on behalf of the Insight-HXMT team:\n\nAt 2026-05-27T06:16:10.000 (T0), Insight-HXMT/HE detected the short burst GRB 260527A/EP260527a, which is also detected by Konus-Wind (D. Svinkin et al., GCN#44722), GECAM-B (Yu et al., GCN #44724), and EP (Yang et al., GCN # 44718).\n\t\nThe Insight-HXMT/HE light curve mainly consists of multiple pulses with a T90 of 0.50 +0.30/-0.11 s. \nThe total counts from this burst is 721 counts.\n\nThe HXMT/HE light curve can be found here:\nhttps://www.bursthub.cn//admin/static/hxmtgrb260527A.png\n\nAll measurements above are made with the CsI detectors 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).
