B. Cenko et al., GCN #43285), SVOM/GRM (Yu et al., GCN #43292).\n\nAccording to the GECAM-B light curve in about 70-6000 keV, this burst mainly consists of multi-pulses with a duration (T90) of 30.0 +6.0/-3.0 s. \n\nThe GECAM-B light curve can be found here:\nhttps://www.bursthub.cn//admin/static/gecambgrb260101A.png\n\nGravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission originally consists of two micro-satellites (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).\n\n",
