A. Goldstein (UAH) reports on behalf of the Fermi GBM Team:
"At 22:10:32.45 UT on 12 November 2010, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 101112A (trigger 311292634 / 101112924)
which was also detected by INTEGRAL (Gotz et al. 2010, GCN 11396)
The GBM on-ground location is consistent with the INTEGRAL position.
The GBM lightcurve consists of a single bright pulse at trigger time
preceded by a smaller pulse ~6 s before trigger time with a total duration
(T90) of about 9.2 s (50-300 keV). The time-averaged spectrum from T0-6.1 s
to T0+4.1 s is best fit by a Band function with Epeak = 105.8 +/- 26.0 keV,
alpha = -0.79 +/- 0.24, and beta = -2.02 +/- 0.15 (Castor C-Stat 420.5 for
359 d.o.f.).
The event fluence (8-1000 keV) in this time interval is
(2.96 +/- 0.21)E-6 erg/cm^2. The 1-sec peak photon flux
measured starting from T0+0.13 s in the 8-1000 keV band
is 8.08 +/- 0.41 ph/s/cm^2.
The spectral analysis results presented above are preliminary;
final results will be published in the GBM GRB Catalog."
