Malacaria (INAF-OAR) reports on behalf of the Fermi Gamma-ray Burst Monitor Team: \n\n\"At 10:11:16.89 UT on 08 July 2026, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 260708A (trigger 805198281/260708424).\nThe Final real-time localization was reported in GCN 45115.\nFermi-LAT also detected GRB 260708A (GCN 45117).\n\nThe GBM light curve displays a sharp peak with a duration (T90)\nof about 62 s (50-300 keV). The time-averaged spectrum\nfrom T0+0.5 to T0+49.7 s is best fit by\na power law function with a power law index of -1.86 +/- 0.01 . \n\nThe event fluence (10-1000 keV) in this time interval is\n(2.14 +/- 0.03)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+0.5 s in the 10-1000 keV band is 19.6 +/- 0.5 ph/s/cm^2.\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/\"",
