Hamburg (UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 07:11:39.96 UT on the 29th of November 2016, the Fermi\nGamma-Ray Burst Monitor triggered and located GRB 161129A\n(trigger 502096303/161129300), which was also detected by\nSwift (Kocevski et al., GCN 20210). The GBM on-ground location\nis consistent with the Swift position. The angle from the Fermi\nLAT boresight is 87 degrees using the Swift position.\n\nThe GBM light curve shows a bright burst, with multiple peaks\nover a duration (T90) of about 36 s (50-300 keV).\nThe time-averaged spectrum from T0+4.8 s to T0+45.7 s is\nbest fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.13 +/- 0.06 and\nthe cutoff energy, parameterized as Epeak, is 197 +/- 21 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(8.4 +/- 0.4)E-06  erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+26 s in the 10-1000 keV band is 5.6 +/- 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.\"",
