Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\nAt 06:26:57.60 UT on 15 April 2024, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 240415A (trigger 734855222/240415269) which was also detected by Swift BAT (M.J. Moss et al. 2024, GCN 36108).\n\nThe Fermi GBM on-ground location (Fermi GBM Team, GCN 36107) is consistent with the Swift BAT position. The angle from the Fermi LAT boresight is 125.0 degrees\n\nThe GBM light curve contains a single emission episode with a duration (T90)\nof about 10 s (50-300 keV). The time-averaged spectrum\nfrom T0-4.1 to T0+6.1 s is best fit by is best fit by a Comptonized Epeak function with Epeak = 42.10 +/- 5.26 keV, and alpha = -1.58 +/- 0.14\n\nThe event fluence (10-1000 keV) in this time interval is (1.8 +/- 0.1)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+0.58 s in the 10-1000 keV band is 7.7 +/- 0.3 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\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/",
