Zhou (IHEP), report on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered in-flight\nby a long bright burst, GRB 210822A, at 2021-08-22T09:18:18.00 UTC\n(denoted as T0), which is also observed by Swift/BAT (GCN #30677).\nIts alert data was downlinked to the ground through the\nshort message service of BeiDou Navigation Satellite System (BDS).\n\nAccording to the GECAM-B light curves in about 30-1000 keV\nfrom BDS alert data, this burst mainly consists of multiple\npulses with a duration of about 15 s.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/gecamb_lc_grd_all_combine_83323099.png\n\nAn automatic localization was calculated using the light curves and \nspectrum,\nand the GECAM location is consistent with the Swift/BAT position within \nthe error.\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).",
