TITLE: GCN CIRCULAR NUMBER: 44040 SUBJECT: GRB 260316A: GECAM-B observation DATE: 26/03/17 15:46:38 GMT FROM: Yue Wang <m18509381757@163.com> Yue Wang, Chao Zheng, Chen-Wei Wang, Shao-Lin Xiong (IHEP) report on behalf of GECAM team: GECAM-B was triggered in-flight by GRB 260316A at 2026-03-16T17:12:53.100 UTC (denoted as T0), which is also detected by Fermi/GBM (Fermi GBM team, GCN #44031) and SVOM/GRM (Yue Wang et. al., GCN #44039). According to the GECAM-B light curves in about 70-6000 keV, this burst mainly consists of a single pulse with a duration (T90) of 2.4 +0.4/-0.4 s. The GECAM-B light curve can be found here: https://www.bursthub.cn//admin/static/gecambgrb260316A.png Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission originally consists of two micro-satellites (GECAM-A and GECAM-B) launched in Dec. 2020. As the third member of GECAM constellation, GECAM-C was launched onboard SATech-01 experimental satellite in July 2022. GECAM mission is funded by the Chinese Academy of Sciences (CAS).
