Zhou (IHEP), report on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered in-flight by a long\nburst, GRB 210719A, at 2021-07-19T02:24:59.500 UTC (denoted as T0).\n\nAccording to the GECAM-B light curves in about 15-3500 keV, \nthis burst mainly consists of multiple pulses with a duration about 400 s.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/LC_2021-07-19T02_24_59.500.png\n\nGECAM-B localized this burst to the following position (J2000):\nRa: 82.64 deg\nDec: 51.02 deg\nErr: 5.16 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 location map could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/tn210719_022608_location.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).",
