GCN Circular 8184
A.J. van der Horst (NASA/ORAU), V. Connaughton and M.S. Briggs (UAH) report on behalf of the Fermi GBM Team: "We have performed time-resolved spectroscopy of GRB 080825C (GCN 8141, GCN 8183). The main emission up to 23 seconds is best fit by the Band function. Time-resolved spectra of this emission period display the commonly observed hard-to-soft spectral evolution, with Epeak decreasing from 170 to 110 keV, while the spectral indices remain roughly constant at alpha ~ -0.4 and beta ~ -2.4, consistent with the time-averaged spectral result (GCN 8141). Weaker emission following this period lasts a further 11 seconds and deviates from this spectral behaviour. The spectrum of this tail over the energy range 8-900 keV is best fit by a single power law with index -1.41 +/- 0.09. The spectral analysis results presented above are preliminary; the final results will be published in the GBM GRB Catalog."
