Dunwoody (UCD), and C.Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\nAt 09:17:15.73 UT on 27 May 2022, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 220527A (trigger 675335840 / 220527387),\nwhich was also detected by the Fermi LAT (Bissaldi et al. 2022, GCN 32131)\nand AGILE (Ursi et al 2022, GCN 32129). The Fermi GBM Final Real-time\nLocalization\n(GCN 32130) is consistent with the Fermi LAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 49\ndegrees.\n\nThe GBM light curve consists of a double peak emission\nwith a duration (T90) of about 10.5 s (50-300 keV).\nThe time-averaged spectrum from T0-0.13 s to T0+21.38 s is best fit by\na Band function with Epeak = 151.6 +/- 2.7 keV,\nalpha = -0.75 +/- 0.02, and beta = -2.55 +/- 0.05.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.69 +/- 0.04)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+7.4 s in the 10-1000 keV band\nis 92.6 +/- 0.7 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/\"",
