GCN Circular 16987
O.J. Roberts (UCD) reports on behalf of the Fermi GBM Team: "At 03:13:18.62 UT on the 29th October 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 141029B (trigger 436245201 / 141029134). The trigger resulted in an Autonomous Repoint Request (ARR) that was accepted and the spacecraft slewed to the GBM in-flight location. The on-ground calculated location, using the GBM trigger data, is RA = 105.2, DEC = +25.1, with an uncertainty of 1.0 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is about 42 degrees. The GBM light curve consists of a multiple episodes with a duration (T90) of about 202.4 s (50-300 keV). The time-averaged spectrum from T0-12.2 s to T0+190.5 s is well fit by a power law function with an exponential high-energy cutoff. The power law index is -1.36 +/- 0.03 and the cutoff energy, parameterised as Epeak, is 191 +/-13 keV. The event fluence (10-1000 keV) in this time interval is (3.800 +/- 0.10)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+78.3 s in the 10-1000 keV band is 20.3 +/- 0.4 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
