Tamura (Kanagawa U),\nN. Cannady (GSFC/UMBC), M. L. Cherry (LSU), S. Ricciarini (U of Florence),\nP. S. Marrocchesi (U of Siena),\nand the CALET collaboration:\n\nThe GRB 251013A (Fermi GBM Final Real-time Localization: Fermi GBM team, GCN Circ. 42213;\nSVOM/GRM observation: Wang et al., GCN Circ. 42218) triggered the CALET Gamma-ray\nBurst Monitor (CGBM) at 08:04:04.90 UTC on 13 October 2025\n(https://cgbm.calet.jp/cgbm_trigger/flight/1444377382/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+0.55 sec, peaks at T+1.32 sec, and ends at T+1.85 sec.\nThe T90 and T50 durations measured by the SGM data are 1.20 +/- 0.16 sec\nand 0.50 +/- 0.11 sec (40-1000 keV), respectively.\n\nThe ground-processed light curve is available at\n\nhttps://cgbm.calet.jp/cgbm_trigger/ground/1444377382/\n\nThe CALET data used in this analysis are provided by\nthe Waseda CALET Operation Center located at Waseda University.",
