Bin-Bin Zhang (UAH) reports on behalf of the Fermi GBM Team:

"At 00:54:00.62 UT on 08 August 2014, the Fermi Gamma-Ray Burst��
Monitor triggered and located GRB 140808A (trigger 429152043/140808038)
for which a possible counterpart was detected by iPTF14eag��
(Singer et al. 2014, GCN 16668). The GBM on-ground location,��
using the Fermi GBM trigger data, is consistent with the��
iPTF14eag location.

The angle from the Fermi LAT boresight is 63 degrees.

The GBM light curve one main episode which consists of several��
overlapping peaks, with a total duration of about 4.7 s (50-300keV).��
The time-averaged spectrum from T0+0 s to T0+5.0 s is well fit by��
a Band function parameterized as alpha=-0.4+/-0.1, beta=-2.9+/-0.3,��
Ep=115.2+/-7.7 keV.

The event fluence (10-1000 keV) in this time interval is
(3.2 +/- 0.2)E-06 erg/cm^2. The 1.024-sec peak photon flux measured
starting from T0+0.5 s in the 10-1000 keV band is 9.3 +/- 0.3 ph/s/cm^2.

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