TITLE: GCN CIRCULAR NUMBER: 11727 SUBJECT: GRB 110213A: Fermi GBM observation DATE: 11/02/14 16:06:55 GMT FROM: Suzanne Foley at MPE S. Foley (MPE) reports on behalf of the Fermi GBM Team: "At 05:17:11.27 UT on 13 February 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110213A (trigger 319267033 / 110213220) which was also detected by the Swift/BAT (D'Elia et al. 2011, GCN 11705). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 101 degrees. The GBM light curve consists of two main pulses with a duration (T90) of about 33 s (50-300 keV). The time-averaged spectrum from T0-3.072 s to T0+31.745 s is well fit by a power law function with an exponential high-energy cutoff. The power law index is -1.44 (+/- 0.05) and the cutoff energy, parameterized as Epeak, is 98.4 (+8.5/-6.9) keV. The event fluence (10-1000 keV) in this time interval is (1.03 +/- 0.03)E-05 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0+18.17 s in the 10-1000 keV band is 17.7 +/- 0.5 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
