Roberts (UCD) reports on behalf of the Fermi GBM Team:\n\nAt 02:43:45.92 UT on October 22nd, 2016, the Fermi Gamma-Ray\nBurst Monitor triggered and located GRB 161022A\n(trigger 498797029/161022114), which was also detected by Swift\n(Stamatikos et al., GCN 20087). The GBM on-ground location is\nconsistent with the Swift position. The angle from the Fermi LAT\nboresight is 131 degrees.\n\nThe GBM light curve shows a weak, FRED-like peak with a duration\n(T90) of about 19 s (50-300 keV). The time-averaged spectrum\nfrom T0-6.1 s to T0+11.3 s is adequately fit by a power law function\nwith an exponential high-energy cutoff. The power law index is\n-0.59 +/- 0.37 and the cutoff energy, parameterized as Epeak,\nis 155.7 +/- 33.2 keV\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.65 +/- 0.24)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-1.3 s in the 10-1000keV band is 2.5 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.",
