TITLE: GCN CIRCULAR NUMBER: 38284 SUBJECT: GRB 241114B: Insight-HXMT/HE detection DATE: 24/11/20 17:34:01 GMT FROM: Chenwei Wang at IHEP <cwwang@ihep.ac.cn> Chen-Wei Wang, Shao-Lin Xiong, Shi-Jie Zheng and Yan-Ting Zhang report on behalf of the Insight-HXMT team: At 2024-11-14T11:05:03 (T0), Insight-HXMT/HE detected a long burst, GRB 241114B. The Insight-HXMT/HE light curve mainly consists of three episodes with a T90 of 25.0 +0.3/-0.5 s. The 1s peak rate, measured from T0+30.5 s, is 7255 cnts/sec. The total counts from this burst is 33848 counts. The HXMT/HE light curve can be found here: https://www.bursthub.cn//admin/static/hxmtgrb241114B.png All measurements above are made with the CsI detectors operating in the regular mode with the energy range of about 80-800 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. Insight-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).
