  "body": "R. Hamburg (USRA) reports on behalf of the Fermi-GBM Team:\n\nSVOM ECLAIRs detected GRB 260914A on 2026-09-14 at 11:12:31 UTC (GCN 45562). There was no Fermi-GBM onboard trigger around this time.\n\nThe GBM Targeted Search [1], the most sensitive coherent search for GRB-like signals in GBM, identified a spatially-consistent transient at 2026-09-14T11:12:30.552 UTC. The Targeted Search event is found most significantly on the 4.096 s timescale with a false alarm rate of 6.1e-5 Hz. The Fermi-MET of this transient is 811077155.552 s. Additionally, the Targeted Search event was found with the highest significance using a soft GRB spectrum (Band function with Epeak = 70 keV, alpha = -1.9, beta = -3.7).\n\n[1] Goldstein et al. 2019 arXiv:1903.12597",
