Bissaldi (INFN Bari) reports on behalf of the Fermi GBM Team:\n\n\n\"At 10:37:38.70 UT on 12 September 2015, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 150912A (trigger 463747062/150912443),\nwhich was also detected by INTEGRAL (Mereghetti et al. 2015, GCN 18291).\nThe GBM on-ground location is consistent with the INTEGRAL position.\n\nThe angle from the Fermi-LAT boresight at the GBM trigger time is 67 degrees.\n\nThe GBM light curve consists of a single peak\nwith a duration (T90) of about 30 s (50-300 keV).\nThe time-averaged spectrum from T0-6 s to T0+22 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff. The power law index is -1.11 +/- 0.10 and\nthe cutoff energy, parameterized as Epeak, is 250 +/- 40 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(4.5 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux, measured\nstarting from T0+2.2 s in the 10-1000 keV band,\nis 2.82 +/- 0.25 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
