Zheng (IHEP),\nreport on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered ground by a short\nbright burst, GRB 211024A, at 2021-10-24T01:34:11.450 UTC (denoted as T0),\nwhich was also detected by Fermi/GBM (GCN 30962).\nAccording to the GECAM-B light curves in about 16-3500 keV, this \nburst mainly consists of a broad pulse with a duration of about 0.1 s.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/tn211024_013411_gb.png\n\nGECAM-B localized this burst to the following position (J2000):\nRa: 25.7 deg \nDec: 1.05 deg\nErr: 28.73 deg (1-sigma, statistical only)\nThe current systematic error of location is estimated to be several degrees \nwhich could be minimized by the ongoing calibration.\n\nThis location is consistent with Fermi/GBM position within the 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).",
