  "body": "Wen-Long Zhang, Shao-Lin Xiong, Xiao-Yun Zhao report on behalf of the GECAM team:\n\nGECAM-B was triggered in-flight by a long burst, GRB 240312A, at 2024-03-12T14:02:10.550 UTC (T0). INTEGRAL/SPI-ACS was also triggered by this burst. \n\nAccording to the GECAM-B light curves, this burst shows single-pulses with a total duration of ~5 sec.\n\nAccording to the in-flight software, GECAM-B localized this burst to the following position (J2000): \nRa: 13.86 deg   \t\nDec: 2.45 deg\nErr: 2.74 deg (1-sigma, statistical only)\n\nThe time-averaged spectrum of GECAM-B realtime data from about T0-0.2 to T0+3.8 s could be\nadequately fit by a Band function with a flux about 2.09E-6 erg/cm^2/s in 20-1000 keV. \n\nWe note that these results are very preliminary. Refined analysis will be reported later.\n\nGravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission originally consists of two microsatellites (GECAM-A and GECAM-B) launched in December 2020. As the third member of GECAM constellation, GECAM-C was launched onboard SATech-01 experimental satellite in July 2022. GECAM mission is funded by the Chinese Academy of Sciences (CAS).",
