Paciesas (UAH) and A.J. van der Horst (NASA/ORAU)\nreport on behalf of the Fermi Gamma-ray Burst Monitor Team:\n\n\n\"At 16:55:46 UT on 5 September 2008, the Fermi GBM triggered\nand located GRB 080905B (trigger 242326547 / 080905705), which was\nalso detected by Swift (Stroh et al., GCN 8182). The on-ground calculated\nlocation, using the Fermi GBM trigger data, is RA = 307.1, Dec = -60.2\n(J2000 degrees) (equivalent to J2000 20h 28m, -60d 12'), with a statistical\nuncertainty of 5.7 degree (radius, 1-sigma containment; there is\nadditionally a systematic error which is currently estimated to be 2 to 3\ndegrees). The angle from the Fermi LAT boresight to the GBM localization\nis 82 degrees. \n\nThis long GRB consists of one main peak at trigger time, possibly a weak\npre-trigger at T-20 s and second peak at T0 + 70 sec and the third from\nT0+80 sec to T0+110 sec similar to the Swift light curve.\n\nThe burst duration (in the energy range 20-1000 keV) T90 is about 159 sec.\n\nThe time-averaged spectrum from T0-20 to T0+110 sec is well fit by a power\nlaw function with index -1.75 +/- 0.12.The fluence (20-1000 keV) is\n4.1(+/-0.3)E-08 erg/cm2and the peak flux (20-1000 keV) is 0.21 +/- 0.02\nph/cm2/s.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the Fermi GBM GRB Catalog.\"",
