  "body": "Wen-Long Zhang, Shao-Lin Xiong, Yan-Qiu Zhang report on behalf of the GECAM team:\n\nGECAM-B was triggered on-ground by a long burst, GRB 240118C, at 2024-01-18T17:23:24.000 UTC (T0), which was also observed by Fermi/GBM (GCN #35576 and GCN #35586) and Swift/BAT-GUANO（GCN #35581）. \n\nAccording to the GECAM-B light curve, this burst consists of  roughly three pulses with a total duration of ~40 sec. \n\nThe GECAM-B ground calculated location (J2000) is:\nRa: 308.64 deg   \nDec: -1.56 deg\nErr: 4.65 deg (1-sigma, statistical only)\nThis GECAM-B localization is consistent with that of Fermi/GBM within the error.\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 Dec. 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).",
