Song, F. J. Lu, S. N. Zhang (IHEP), report on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered in-flight by\na bright short burst (trig# 84938908) at 2021-09-10T02:08:28.800 UTC (T0),\nIts alert data was promptly downlinked to the ground through the short\nmessage service of BeiDou Navigation Satellite System (BDS). The time latency\nof the first BeiDou message relative to the trigger time is about 1 minute.\n\nAccording to the GECAM-B light curves in about 15-65 keV, this burst mainly\nconsists of a single pulse with a duration about 100 ms. The location is consistent\nwith SGR J1935+2154 within the error.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/utn210910_020828_GECAMb.png\n\nPlease note that all GECAM results here are preliminary. The final analysis\nwill be published in journal papers or GECAM online catalog.\n\nGravitational wave high-energy Electromagnetic Counterpart All-sky Monitor\n(GECAM) mission consists of two small satellites (GECAM-A and GECAM-B) in\nLow Earth Orbit (600 km, 29 deg), launched on Dec 10, 2020 (Beijing Time),\nwhich was funded by the Chinese Academy of Sciences (CAS).",
