Circular_text TITLE: GCN CIRCULAR NUMBER: 8496 SUBJECT: GRB 081102B: Fermi GBM detection DATE: 08/11/07 17:26:42 GMT FROM: Andreas von Kienlin at MPE A. von Kienlin (MPE) and E. Bissaldi (MPE) report on behalf of the Fermi GBM Team: "At 08:45:00.51 UT on 02 November 2008, the Fermi GBM triggered and located GRB 081102B (trigger 247308301/ 081102365). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 231.2, Dec = 35.2 (J2000 degrees, equivalent to J2000 15h 25m, 35d 12'), with a statistical uncertainty of 6.1 degrees (radius, 1-sigma containment; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 53 degrees. The GBM light curve shows a double peak with a duration (T90) of about 2.2 s (8-1000 keV). The time-averaged spectrum from T0-0.226 s to T0+0.798 s (first peak) is well fit by a simple power law function with index -1.07 +/- 0.06 (chi squared 247 for 243 d.o.f.). The event fluence (8-1000 keV) in the same time interval is (1.12 +/- 0.04)E-06 erg/cm^2. The 1-sec photon flux measured starting from T0-0.226 s in the 8-1000 keV band is 3.68 +/- 0.14 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
