Meegan (UAH)\n report on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\n\"At 10:46:08.33 UT on 25 May 2023, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 230525A (trigger 706704373/230525449).\nThe Fermi GBM Final Real-time Localization was reported in GCN 33877.\n\nThe angle from the Fermi LAT boresight is 19 degrees.\n\nThe GBM light curve consists of single peak with a duration (T90)\nof 0.12 s (50-300 keV). The time-averaged spectrum\nfrom T0-0.06 to T0+0.06 s is best fit by\na power law function with an exponential high-energy cutoff.\nThe power law index is -0.80 +/- 0.09 and the cutoff energy,\nparameterized as Epeak, is 789 +/- 148 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(8.6 +/- 0.4)E-07 erg/cm^2. The 64-ms peak photon flux measured\nstarting from T0-0.064 s in the 10-1000 keV band is 25 +/- 1 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/\""
