  "body": "Chen-Wei Wang, Shao-Lin Xiong report on behalf of the GECAM team:\nGECAM-B was triggered in-flight by a long burst, GRB 231122B \nat 2023-11-22T15:12:41.050 UTC (denoted as T0), \nwhich was also detected by CALET/GBM (trigger num 1384701074).\n\nAccording to the realtime alert data of GECAM-B, this burst mainly consists of many pulses\nwith a duration of about 50 s. The time-averaged spectrum from T0 to T0+17 s \ncould be adequately fit by a power law with high energy exponential cutoff function \nwith a fluence of about 9.8E-6 erg/cm2 in 20-1000 keV.\n\nUsing the automatic on-ground localization pipeline with the realtime alert data, \nGECAM-B localized this burst to the following position (J2000): \nRa: 106.2 deg \nDec: -21.3 deg\nErr: 1.5 deg (1-sigma, statistical only)\n\nGravitational wave high-energy Electromagnetic Counterpart All-sky Monitor\n(GECAM) mission originally consists of two micro-satellites (GECAM-A and GECAM-B)\nlaunched in Dec. 2020. As the third member of GECAM constellation, \nGECAM-C was launched onboard SATech-01 experimental satellite in July 2022. \nGECAM mission is funded by the Chinese Academy of Sciences (CAS).",
