Marrocchesi (U of Siena),\nand the CALET collaboration:\n\nThe CALET Gamma-ray Burst Monitor (CGBM) detected GRB 260410A \n(Fermi GBM Final Real-time Localization: Fermi GBM team, GCN #44252; \nFermi-LAT detection: Holzmann Airasca et al., GCN #44253; Fermi GBM \nObservation: Hamburg et al., GCN #44258) at 07:03:56.88 UTC on 10 April 2026\n(https://cgbm.calet.jp/cgbm_trigger/flight/1459839839/index.html).\nThe burst signal was seen by all CGBM detectors.  \n\nThe burst light curve shows a short pulse starting\nat T+0.06 s, peaking at T+0.18 s, and ending at T+0.29 s.\nThe T90 and T50 durations measured with the SGM data are 0.21 +/- 0.04 s\nand 0.10 +/- 0.03 s (40-1000 keV), respectively.\n\nThe ground-processed light curve is available at\n\nhttps://cgbm.calet.jp/cgbm_trigger/ground/1459839839/\n\nThe CALET data used in this analysis were provided by\nthe Waseda CALET Operation Center located at Waseda University.",
