  "body": "Zheng-Hang Yu, Shao-Lin Xiong (IHEP) report on behalf of GECAM team:\n\nGECAM-B detected a burst GRB 260920B/EP260920b at 2026-09-20T14:11:37.000 UTC (denoted as T0). According to the GECAM-B light curves in about 70-6000 keV, this burst consists of two main episodes with multiple pulses with a T90 of 162.0 +118.0/-10.0 s.\n\nThe GECAM-B light curve can be found here:\nhttps://www.bursthub.cn/gcn/2026/9/gecambgrb260920B.png\n\n\nGravitational 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).",
