Poolakkil (UAH) and C.Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 22:24:42.74 UT on 15 July 2022, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 220715B (trigger 679616687 / 220715934), which was\nalso detected by the Swift/BAT (E. Troja et al. 2022, GCN 32405)\n\nThe Fermi GBM Final Real-time Localization (GCN 32404) is consistent with\nthe Swift position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 69\ndegrees.\n\nThe GBM light curve consists of multiple peaks\nwith a duration (T90) of about 40 s (50-300 keV).\nThe time-averaged spectrum from T0-1.024 s to T0+43.008 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.09 +/- 0.23  and\nthe cutoff energy, parameterized as Epeak, is 118 +/- 28 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(2.2 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-0.8 s in the 10-1000 keV band\nis 2.5 +/- 0.2 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/\"",
