Meegan (UAH) report on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\n\"At 05:48:03.33 UT on 30 October 2024, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB241030A (trigger 751960088/241030242).\nwhich was also detected by Swift-BAT (Klingler et al. 2024, GCN 37956), SVOM-GRM (Wang et al. 2024, GCN 37972), and Konus-Wind (Ridnaia et al. 2024, GCN 37982)\nThe Fermi GBM on-ground location is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight is 17 degrees.\n\nThe GBM light curve consists of multiple emission episodes with a duration (T90)\nof about 166 s (50-300 keV). The time-averaged spectrum\nfrom T0-21 to T0+217 s is best fit by\na Band function with Epeak = 129 +/- 7 keV,\nalpha = -1.35 +/- 0.02, and beta = -2.31 +/- 0.08.\n\nThe event fluence (10-1000 keV) in this time interval is\n(6.235 +/- 0.095)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+147 s in the 10-1000 keV band is 20 +/- 0.4 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/\"",
