Meegan (UAH) report on behalf of\nthe Fermi Gamma-ray Burst Monitor Team:\n\n\"At 23:48:54 UT on 22 August 2023, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 230822A (trigger 714440939/230822992).\nwhich was also detected by Swift/BAT-GUANO (DeLaunay et al. 2023, GCN 34529).\nThe Fermi GBM Final Real-Time Localization was reported previously (Fermi GBM Team 2023, GCN 34521).\n\nThe angle from the Fermi LAT boresight is 78 degrees.\n\nThe GBM light curve consists of a single weak emission episode with a duration (T90)\nof about 0.9 s (50-300 keV). The time-averaged spectrum\nfrom T0-0.448 to T0 s is best fit by\na simple power law function with index -1.3 +/- 0.2.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.7 +/- 2.6)E-08 erg/cm^2. The 64-ms peak photon flux measured\nstarting from T0-1.7 s in the 10-1000 keV band is 2.2 +/- 0.9 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/\"",
