Marrocchesi (U of Siena),\nand the CALET collaboration:\n\nThe CALET Gamma-ray Burst Monitor (CGBM) was triggered by GRB 250313A \nat 14:34:30.53 UTC on 13 March 2025, which is also detected by Fermi-GBM \n(Fermi-GBM team, GCN #39703), Fermi-LAT (Di Lalla et al., GCN #39711),\nAstroSat CZTI (Dasgupta et al., GCN #39714), SVOM/GRM (Wang et al, GCN #39716)\nand Konus-Wind (Frederiks et al., GCN #39721). \n(https://cgbm.calet.jp/cgbm_trigger/flight/1425911606/index.html).\nThe burst signal was seen by all CGBM detectors.  \n\nThe burst light curve shows a multi-peaked structure that starts\nat T+3.1 sec, peaks at T+11.3 sec, and ends at T+17.4 sec.\nThe T90 and T50 durations measured by the SGM data are 10.1 +/- 0.5 sec\nand 4.8 +/- 0.3 sec (40-1000 keV), respectively.\n\nThe ground-processed light curve is available at\n\nhttps://cgbm.calet.jp/cgbm_trigger/ground/1425911606/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at Waseda University.\n",
