TITLE: GCN CIRCULAR NUMBER: 39034 SUBJECT: GECAM-A detection of a bright burst from SGR 1E1841-045 DATE: 25/01/26 02:47:44 GMT FROM: zhangjinpeng@ihep.ac.cn Jin-Peng Zhang (IHEP), Shao-Lin Xiong (IHEP), Peng Zhang (IHEP), Yan-Qiu Zhang (IHEP), Chao Zheng (IHEP), Chen-Wei Wang (IHEP) report on behalf of the GECAM team: GECAM-A detected a bright burst from SGR 1E1841-045 at 2025-01-23T08:47:19.600 UTC (denoted as T0), which was also detected by Konus-Wind (GCN 39024), Fermi/GBM (GBM trigger 759314844), and SVOM/GRM. The location is consistent with SGR 1E1841-045 by IPN triangulation (GCN 39022). According to the GECAM-A light curves in about 15-70 keV, this burst mainly consists of a single pulse with a duration of about 0.2 s. The GECAM light curve could be found here: https://www.bursthub.cn//admin/static/gasgr_250123_084719.png Please note that all GECAM results here are preliminary. The refined analysis will be reported later. Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission consists of two small satellites (GECAM-A and GECAM-B) in Low Earth Orbit (600 km, 29 deg), launched on Dec 10, 2020 (Beijing Time), which was funded by the Chinese Academy of Sciences (CAS).
