GCN Circular 8477
C. Kouveliotou (NASA/MSFC) and M.S. Briggs (UAHuntsville) report on behalf of the Fermi GBM Team: At 20:14:42.77 UT on 02 November 2008, the Fermi GBM triggered and located a very soft and bright event (trigger 247349683 / 081102844). The event location was RA = 217.6 deg, dec = -15.7 deg (+/- 1.1 deg), in excellent agreement with the Sun location. The time of the event coincides with the solar activity reported in the GOES solar reports (event 9790: onset at 2012 UT, max at 2015 UT, end at 2017, B5.7 flare). This is the first GBM detection of a solar flare; future detections will not be reported in a GCN Circular, unless they exhibit special characteristics. The GBM light curve shows a multiple peak event lasting approximately 177 s (8-30 keV). The time-averaged spectrum from T0-13.824 s to T0+163.33 s is best fit by a single power law model with index -6.55 +/- 0.03 (chi squared 255 for 120 d.o.f.). The event fluence (8-30 keV) in this time interval is (1.54 +/- 0.03) E-4 erg/cm^2. The spectral analysis results presented above are preliminary.
