report on behalf of the Fermi GBM Team:
"At 16:43:15.61 UT on 08 Oct. 2010, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 101008A (trigger 308248997 / 101008697).
The burst was also detected by the SWIFT-BAT
(W. H. Baumgartner et al. 2010, GCN 11318)
The GBM on-ground location is consistent with the Swift position.
The angle from the Fermi LAT boresight is 79 degrees.
The GBM light curve shows a fast rise - slow decay peak
with a duration (T90) of about 7 s (50-300 keV).
The time-averaged spectrum from T0-1.536 s to T0+5.376 s is
best fit by a simple power law function with index -1.42 +/- 0.03
(C-stat 1249.1 for 612 d.o.f.).
The event fluence (10-1000 keV) over the above time interval is
(2.016 +/- 0.083)E-6 erg/cm^2. The 0.064-sec peak photon flux measured
starting from T0+1.344 s in the 10-1000 keV band
is 4.90 +/- 0.84 ph/s/cm^2.
The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog."
