Meegan (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 12:21:41.87 UT on 29 January 2019, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 190129A (trigger 570457306 / 190129515),\nwhich was also detected by MAXI/GSC (Nakahira et al. 2019, GCN 23806).\nThe GBM on-ground location is consistent with the MAXI/GSC position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 118\ndegrees.\n\nThe GBM light curve shows/consists of a single peak\nwith a duration (T90) of about 8.7 s (50-300 keV).\nThe time-averaged spectrum from T0-1 s to T0+4 s is\nadequately fit by\na power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.37 +/- 0.23  and\nthe cutoff energy, parameterized as Epeak, is 78 +/- 19 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(9 +/- 1)E-07 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0-0.38 s in the 10-1000 keV band\nis 3.7 +/- 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.\"",
