Ricciarini (U of Florence),\nand the CALET collaboration:\n\nThe GRB 251001C (Glowbug gamma-ray detection: Cheung et al., GCN Circ. 42049) \ntriggered the CALET Gamma-ray Burst Monitor (CGBM) at 15:07:25.84 UTC on 1 October 2025\n(https://cgbm.calet.jp/cgbm_trigger/flight/1443366004/index.html).\nThe burst signal was seen by only the SGM detector.  \n\nThe burst light curve shows a single pulse that starts\nat T+0.2 sec, peaks at T+1.0 sec, and ends at T+2.4 sec.\nThe T90 and T50 durations measured by the SGM data are 2.0 +/- 0.1 sec\nand 0.7 +/- 0.2 sec (40-1000 keV), respectively.\n\nThe ground-processed light curve is available at\n\nhttps://cgbm.calet.jp/cgbm_trigger/ground/1443366004/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at Waseda University.\n",
