  "body": "Jia-Cong Liu, Shao-Lin Xiong, Peng Zhang, Yan-Qiu Zhang,  Chen-Wei Wang (IHEP) report on behalf of the GECAM team:\n\nGECAM-A detected a long burst, GRB 250225B, at 2025-02-25T19:39:13 UTC (denoted as T0), which was also observed by Swift/BAT (H. A. Krimm et al. 2025, GCN 39473), \nSVOM/GRM (Yan-Qiu Zhang et al. 2025, GCN 39493), Fermi/GBM (M. Godwin et al. 2025, GCN 39502), and Konus-Wind (A. Tsvetkova et al. 2025, GCN 39498). \n\nAccording to the GECAM-A light curves in about 50-200 keV, this burst mainly consists of multiple pulses with a T90 of about 63.2 ± 2.5 s.\n\nThe GECAM light curve can be found here:\nhttps://www.bursthub.cn//admin/static/gecamgrb250225B.png\n\nWe note that these results are preliminary. Refined analysis will be reported.\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).",
