Bissaldi (Politecnico & INFN Bari)\nreport on behalf of the Fermi GBM Team:\n\n\"At 01:32:28.08 UT on 06 December 2016, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 161206A (trigger 502680752/161206064).\nThe on-ground calculated location, using the GBM trigger\ndata, is RA = 0.94, DEC = -34.02 (J2000 degrees),\nwith an uncertainty of 1 degree (radius, 1-sigma containment,\nstatistical only; there is additionally a systematic\nerror which we have characterized as a core-plus-tail model, with 90% of\nGRBs having a 3.7 deg error and a small tail suffering a larger than 10 deg\nsystematic error [Connaughton et al. 2015, ApJS, 216, 32]).\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 63\ndegrees.\n\nThe GBM light curve shows multiple peaks\nwith a duration (T90) of about 34 s (50-300 keV).\nThe time-averaged spectrum from T0-9 s to T0+25 s is\nbest fit by a Band function with Epeak = 309 +/- 15 keV,\nalpha = -0.85 +/- 0.02, and beta = -2.11 +/- 0.05.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.92 +/- 0.04)E-05 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+9.6 s in the 10-1000 keV band\nis 13.5 +/- 0.3 ph/s/cm^2.\n\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
