Cheung et al., GCN #44237), CALET (M. L. Cherry et al., GCN #44242) and Insight-HXMT/HE (Hao-Xuan Guo et al., GCN #44245).\n\nAccording to the GECAM-A light curves in about 40-6000 keV, this burst mainly consists of a single pulse with a duration (T90) of 19.5 +4.5/-6.5 s.\n\nThe GECAM-A light curve can be found here:\nhttps://www.bursthub.cn//admin/static/gecamagrb260407A.png\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.\nAs 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",
