TITLE: GCN CIRCULAR NUMBER: 13560 SUBJECT: GRB 120729A: Fermi GBM observation DATE: 12/08/02 12:40:37 GMT FROM: Arne Rau at MPE Arne Rau (MPE) reports on behalf of the Fermi GBM Team: "At 10:56:12.67 UT on 29 July 2012, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 120729A (trigger 365252175 / 120729456) which was also detected by the Swift/BAT (Ukwatta et al. 2012, GCN 13530). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 83 degrees. The GBM light curve shows a single pulse with a duration (T90) of about 25 s (50-300 keV). The time-averaged spectrum from T0-3.6 s to T0+17.9 s is best fit by a simple power law function with index -1.49 +/- 0.05. The event fluence (10-1000 keV) in this time interval is (5.1 +/- 0.1)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+1.2 s in the 10-1000 keV band is 5.2 +/- 0.3 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
