Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 17:24:49.21 UT on 10 January 2019, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 190110A(trigger 568833894/ 190110726),\nwhich was also detected by the Swift/BAT (Sbarufatti et al. 2019, GCN\n23670).\nThe GBM on-ground location is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight\nat the GBM trigger time is 50 degrees.\n\nThe GBM light curve consists of a single bright peak\nwith a duration (T90) of about 9 s (50-300 keV).\nThe time-averaged spectrum from T0-2.04 s to T0+10.24 s is\nbest fit by a Band function with Epeak = 73 +/- 8 keV,\nalpha = -0.44 +/- 0.20 and beta = -2.12 +/- 0.08.\n\nThe event fluence (10-1000 keV) in this time interval is\n(5.331 +/- 0.209)E-06 erg/cm^2. The 1-sec peak photon flux\nmeasured starting from T0+3.71 s in the 10-1000 keV band\nis 14.7 +/- 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.\"",
