Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 19:33:33.55 UT on 22 October 2022, the Fermi Gamma-Ray Burst Monitor\n(GBM)\ntriggered and located GRB 221022A (trigger 688160018 / 221022815, GCN 32816)\nwhich was also detected by the Swift/BAT- GUANO (Tohuvavohu et al. 2022,\nGCN 32824).\nThe Fermi GBM Final Real-time Localization is consistent\nwith the Swift-BAT GUANO position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 115\ndegrees.\n\nThe GBM light curve consists of a single peak followed\nby some extended emission with a duration (T90) of about 7 s (50-300 keV).\nThe time-averaged spectrum from T0-3.07 s to T0 s\nis best fit by a simple power law function with\nindex -1.39 +/- 0.15.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.64 +/- 0.98)E-07  erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-1.6 s in the 10-1000 keV band\nis 3.3 +/- 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:\nhttps://heasarc.gsfc.nasa.gov/W3Browse/fermi/fermigbrst.html\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support\nPage:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
