Bissaldi (MPE)\nreport on behalf of the Fermi GBM Team: \n\n\"At 08:23:05.29 UT on 25 October 2008, the Fermi GBM triggered and located\nGRB 081025 (trigger 246615786 / 081025349) which was also detected by the\nSWIFT-BAT Slew Survey (A. Copete et al. 2008, GCN 8409) and followed up by\nSWIFT-XRT (J. Mao et al. 2008, GCN 8411). The GBM on-ground location is\nconsistent with the Swift position. \n\nThe GBM light curve shows a multipeaked structure with a duration (T90) of\nabout 45 s (8-1000 keV). The time-averaged spectrum from T0-1.536 s to \nT0+24.064 s is best fit by an exponentially cutoff power law model with \nEpeak = 251 +/- 25 keV, and index -0.35 +/- 0.13 (chi squared 736 for 700 \nd.o.f.). The event fluence (8-1000 keV) in this time interval is \n(7.1 +/- 0.5)E-06 erg/cm^2. The 1-sec photon flux measured from T+2.56 sec\nin the 8-1000 keV band is 4.50 +/- 0.22  ph/cm2/sec. A Band function fit\nthe spectrum equally well (chi squared 732 for 699 d.o.f.) with \nEpeak= 200 +/- 33 keV, alpha = 0.15 +/- 0.22 and beta = -2.05 +/- 0.25. \n\nThe spectral analysis results presented above are preliminary; final results\n\nwill be published in the GBM GRB Catalog.\"",
