TITLE: GCN CIRCULAR NUMBER: 11344 SUBJECT: GRB 101011A: Fermi GBM detection DATE: 10/10/16 23:51:41 GMT FROM: Michael Burgess at UAH Michael Burgess (UAH) reports on behalf of the Fermi GBM Team: "At 16:58:36.53 UT on 11 October 2010, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 101011A (trigger 308509118 /101011707) which was also detected by the SWIFT-BAT (Cannizzo et al. 2010, GCN 11331) The GBM on-ground location is consistent with the Swift position. This burst was also independently detected by INTEGRAL SPI-ACS. The angle from the Fermi LAT boresight is 144 degrees. The GBM light curve consists of a several moderately bright peaks with a duration (T90) of about 35.01 s (8-1000 keV). The time-averaged spectrum from T0-0.768 s to T0+35.78 s is best fit by a power law function with an exponential high energy cutoff. The power law index is -.49 +/- .25 and the cutoff energy, parameterized as Epeak, is 296.6 +/- 49.4 keV The event fluence (8-1000 keV) in this time interval is (5.24 +/- .39)E-6 erg/cm^2. The .256-sec peak photon flux measured starting from T0+25.15 s in the 8-1000 keV band is 5.16 +/- 1.6 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog." ________________________________ J.
