A.J. van der Horst (NASA/ORAU) and V. Connaughton (UAH) report on behalf of the Fermi GBM Team: "At 14:13:48 UT on 25 August 2008, the Fermi GBM triggered and located GRB 080825C (trigger 241366429 / 080825.593). The on-ground calculated location, using the GBM trigger data, is RA = 232.2, Dec = -4.9 (J2000 degrees, equivalent to 15h 29m, -4d 54'), with an uncertainty of 1.5 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 60 degrees. This GRB has several peaks, with T90 (50-300 keV) = 22 s and T50 (50-300 keV) = 12 s. The time-averaged spectrum (8-910 keV) from T0 to T0+22.1 s is best fit by a Band function with Epeak = 155 +/- 5 keV, alpha = -0.39 +/- 0.04, and beta = -2.34 +/- 0.09. The fluence (50-300 keV) is 2.4E-5 erg/cm^2. The spectral analysis results presented above are preliminary; the final results will be published in the GBM GRB Catalog."
