Zheng (IHEP), report on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered in-flight by\na bright short burst (trig# 88823384) at 2021-10-25T01:09:44.250 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 BDS alert data, this burst mainly consists of\na single pulse with a duration of about 50 ms. \nUsing the light curves and spectrum in the BDS alert data, \nGECAM-B localized this burst to the following position (J2000): \nRa: 244.40 deg \nDec: -64.997 deg\nErr: 17.63 deg (1-sigma, statistical only)\nThe current systematic error of location is estimated to be several degrees.\n\nThis location is consistent with SGR J1555.2-5402 within the error.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/gecamb_lc_grd_all_combine_88823384.png\n\nAs the detailed science data are downloaded, all analyses would be improved.\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).",
