Meegan (UAH) report on behalf of\nthe Fermi Gamma-ray Burst Monitor Team:\n\n\"At 15:33:00.41 UT on 15 February 2024, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 240215A (trigger 729703985/240215648),\nwhich was also detected by Swift/BAT-GUANO (J. DeLaunay et al. 2024, GCN 35733).\nThe Fermi GBM on-ground location is consistent with the Swift/BAT-GUANO position.\n\nThe angle from the Fermi LAT boresight is 67 degrees.\n\nThe GBM light curve consists of a pulse followed by weak emission with a duration (T90)\nof about 57 s (50-300 keV). The time-averaged spectrum\nfrom T0-4.1 to T0+60.4 s is best fit by\na simple power law function with index -1.77 +/- 0.06.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.6 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-0.064 s in the 10-1000 keV band is 1.9 +/- 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 Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
