Meegan (UAH) report on behalf of\nthe Fermi Gamma-ray Burst Monitor Team:\n\n\"At 16:45:37.62 UT on 15 January 2024, the Fermi Gamma-ray Burst Monitor (GBM)\ntriggered and located GRB 240115B (trigger 727029942/240115698). GRB 240115B\nwas also localized by INTEGRAL (S. Mereghetti et al. 2024, GCN 35541).\n\nThe angle from the Fermi LAT boresight is 97 degrees.\n\nThe GBM light curve consists of multiple peaks of emission\nwith a duration (T90) of about 163 s (50-300 keV). \nThe time-averaged spectrum from T0-26.63 s to T0+47.11 s \nis best fit by a power law function with an exponential\nhigh-energy cutoff. The power law index is -0.73 +/- 0.11,\nand the cutoff energy parameterized as Epeak, is 125 +/- 10.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.13 +/- 0.26)E-06 erg/cm^2. The 1-sec peak photon flux measured\n starting from T0+17.6 s in the 10-1000 keV band is 2.6 +/- 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\n\nFor Fermi GBM data and info, please visit the official Fermi GBM Support Page:\nhttps://fermi.gsfc.nasa.gov/ssc/data/access/gbm/\"",
