Meegan (both UAH)\nreport on behalf of the Fermi GBM Team:\n\n\"At 20:19:51.61 UT on 29 October 2020, the Fermi Gamma-Ray Burst Monitor (GBM)\ntriggered and located GRB 201029A (trigger 625695596 / 201029847)\nwhich was also detected by the Swift/BAT (Dichiara et al., GCN 28803).\nThe GBM on-ground location is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 59 degrees.\n\nThe GBM light curve consists of a broad peak\nwith a duration (T90) of about 78 s (50-300 keV).\nThe time-averaged spectrum from T0-8.2 s to T0+34.8 s is\nadequately fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -1.03 +/- 0.10 and\nthe cutoff energy, parameterized as Epeak, is 647 +/- 230 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.59 +/- 0.14)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+1.4 s in the 10-1000 keV band\nis 1.4 +/- 0.2 ph/s/cm^2.\n\n\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/\"",
