Jiang et al., GCN #39482) and INTEGRAL/SPI-ACS (triNum #11070).\n\nAccording to the GECAM-B light curves in about 5-2000 keV, this burst mainly consists of multiple pulses with a duration (T90) of about 63.5 +/- 11.7 s.\n\nThe GECAM light curve could be found here:\nhttps://www.bursthub.cn//admin/static/gecamgrb250226A.png\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).\n",
