Meegan (UAH) and A. von Kienlin (MPE)\nreport on behalf of the Fermi GBM Team:\n\n\"At 10:04:10.11 UT on 13 January 2017, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 170113A (trigger 505994655 / 170113420).\nwhich was also detected by the Swift/BAT (Evans et al., GCN 20446).\nThe GBM on-ground location is consistent with the Swift position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger\ntime is 145 degrees.\n\nThe GBM light curve shows a single pulse\nwith a duration (T90) of about 49 s (50-300 keV).\nThe time-averaged spectrum from T0-10 s to T0+47 s is\nadequately fit by a simple power law function with\nindex -2.05 +/- 0.08.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.8 +/- 0.4)E-6 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+4.5 s in the 10-1000 keV band\nis 2.9 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
