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 a long\nburst, GRB 211110A, at 2021-11-10T03:26:29.600 UTC (denoted as T0).\n\nGECAM alert data was downlinked to the ground through the short message\nservice of BeiDou Navigation Satellite System (BDS) within ~60 s after T0.\n\nAccording to the BDS alert data, this burst mainly consists of a broad pulse\nwith a duration of about 15 s. \n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/multiLCvsE_2021-11-10T033A263A28.450.png\n\nUsing the automatic on-ground localization pipeline with the BDS alert data, \nGECAM-B localized this burst to the following position (J2000): \nRa: 324.19 deg \nDec: -3.15 deg\nErr: 7.59 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\nThe GECAM preliminary location could be found here: \nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/gecamb_skymap_bdm_90213989_V01.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).",
