Marrocchesi (U of Siena),\nand the CALET collaboration:\n\nThe CALET Gamma-ray Burst Monitor (CGBM) detected GRB 260611B\nat 21:32:32.02 UTC on 11 June 2026 (trigger #1465248636;\nhttps://cgbm.calet.jp/cgbm_trigger/flight/1465248636/index.html).\nA CGBM Notice was distributed in near real time.\n\nThis event was also reported by Fermi GBM (Fermi GBM Team., GCN #44917).\n\nThe burst signal was seen by all CGBM detectors.\nThe burst light curve shows a multi-peaked structure starting\nat T+0.2 s, peaking at T+14.7 s, and ending at T+28.4 s.\nThe T90 and T50 durations measured with the SGM data are 24.7 +/- 0.9 s\nand 13.5 +/- 1.2 s in the 40-1000 keV band, respectively.\n\n\nThe ground-processed light curve is available at:\nhttps://cgbm.calet.jp/cgbm_trigger/ground/1465248636/\n\nThe CALET data used in this analysis were provided by\nthe Waseda CALET Operation Center located at Waseda University.",
