Trigg (NPP ORAU, NASA MSFC) reports on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\n\"At 16:12:21.43 UT on 06 July 2026, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 260706A (trigger 805047146/260706675),\nwhich was also detected by SVOM/ECLAIRs (J. Alaux et al. 20026, GCN 45089).\nThe Fermi GBM on-ground location is consistent with the SVOM/ELCAIRs position.\n\nThe angle from the Fermi LAT boresight is 43 degrees.\n\nThe GBM light curve displays two peaks with a duration (T90)\nof about 17 s (50-300 keV). The time-averaged spectrum\nfrom T0+0.001 to T0+30.616 s is best fit by\na power law function with an exponential high-energy cutoff.\nThe power law index is -1.13 +/- 0.01 and the cutoff energy,\nparameterized as Epeak, is 47.1 +/- 0.6 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.18 +/- 0.08)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+15 s in the 10-1000 keV band is 5.3 +/- 0.3 ph/s/cm^2.\n\nA Band function fits the spectrum equally well\nwith Epeak= 39.1 +/- 0.5 keV, alpha = -0.71 +/- 0.01 and beta = -2.63 +/- 0.03.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
