TITLE: GCN CIRCULAR NUMBER: 38326 SUBJECT: GECAM detection of a short burst from SGR 1830 DATE: 24/11/26 15:41:19 GMT FROM: zhengchao_astro@foxmail.com C. Zheng (IHEP), Shao-Lin Xiong (IHEP), Peng Zhang (IHEP), Yan-Qiu Zhang (IHEP), Chen-Wei Wang (IHEP) report on behalf of the GECAM team: GECAM-B detected a short burst at 2024-11-26T05:12:17.510 UTC (denoted as T0). According to the GECAM-B light curves in about 20-100 keV, this burst mainly consists of a single pulse with a duration of about 0.08 s. The GECAM light curve could be found here: https://www.bursthub.cn//admin/static/gbsgr_241126_051217.png Using the automatic on-ground localization pipeline with the daily data, GECAM-B localized this burst to the following position (J2000): Ra: 278.64 deg Dec: -11.35 deg Err: 2.95 deg (1-sigma, statistical only) The location is consistent with the SGR 1830 within the margin of error. The GECAM preliminary location could be found here: https://www.bursthub.cn//admin/static/gbsgr_241126_051217_loc.png Please note that all GECAM results here are preliminary. The final analysis will be published in journal papers or GECAM online catalog. 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).
