Circular_text TITLE: GCN CIRCULAR NUMBER: 9619 SUBJECT: GRB 090706: Fermi GBM detection DATE: 09/07/06 15:06:24 GMT FROM: Arne Rau at MPE Arne Rau (MPE) reports on behalf of the Fermi GBM Team: "At 06:47:40.43 UT on 06 July 2009, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 090706 (trigger 268555662 / 090706283). The on-ground calculated location, using the GBM trigger data, is RA = 205.1, DEC = -47.1 (J2000 degrees, equivalent to 13 h 40 m, -47 d 06 '), with an uncertainty of 3.0 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 20 degrees. The GBM light curve consists of two peaks with a duration (T90) of about 100 s (8-1000 keV). The time-averaged spectrum from T0-34.8s to T0+7.2 s is adequately fit by a simple power law function with index -2.16 +/- 0.09 (chi squared 410 for 339 d.o.f.). The event fluence (8-1000 keV) in this time interval is (1.5 +/- 0.1)E-06 erg/cm^2. The 4-sec peak photon flux measured starting from T0-30.7 s in the 8-1000 keV band is 1.24 +/- 0.05 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
