Liang, Q. Luo, J. C. Liu, \nL. M. Song, F. J. Lu, S. N. Zhang (IHEP), report on behalf of GECAM team:\n\nDuring the commissioning phase, GECAM-B was triggered ground by a short\nbright burst, GRB 210923B, at 2021-09-23 02:11:29.000 UTC (denoted as T0),\nwhich was also detected by Konus-Wind.\nAccording to the GECAM-B light curves in about 15-3500 keV, this \nburst mainly consists of a broad pulse with a duration of about 0.679 s.\n\nThe GECAM light curve could be found here:\nhttp://twiki.ihep.ac.cn/pub/GECAM/GRBList/utn210923_021129_GECAMb_lc.png\n\nGECAM-B localized this burst to the following position (J2000):\nRa: 287.25 deg \nDec: -12.03 deg\nErr: 6.29 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\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).",
