reports on behalf of the Fermi GBM Team:


"At 12:31:15.91 UT on 14 October 2016, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 161014A (trigger 498141079 / 161014522),
which was also detected by the Swift/BAT (Racusin et al. 2016, GCN 20035).
The GBM on-ground location is consistent with the Swift position.

The angle from the Fermi LAT boresight at the GBM trigger time is 69 degrees.

The GBM light curve shows multiple peaks with a duration (T90) of
about 37 s (50-300 keV).
The time-averaged spectrum from T0-6 s to T0+23 s is
adequately fit by a power law function with an exponential
high-energy cutoff. The power law index is -0.74 +/- 0.09 and
the cutoff energy, parameterized as Epeak, is 167 +/- 15 keV.
The event fluence (10-1000 keV) in this time interval is
(5.4 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured
starting from T0+7 s in the 10-1000 keV band
is 5.7 +/- 0.3 ph/s/cm^2.


The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog."
