Zheng (IHEP),\nreport on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered in-flight by a \nlong bright burst, GRB 211229B, at 2021-12-29T22:18:43.150 UTC (denoted as T0)���\nwhich was also observed by Fermi/GBM (GCN #31336).\n\nThis burst mainly consists of multiple pulses with duration of about 15 s.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/211229B_LightCurve.png\n\nThe GECAM preliminary location could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/SkyMap.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).",
