N. Morrell, on behalf of the Carnegie Supernova Project, reports on spectroscopy (range 380-920 nm) obtained on Sept. 28.39 UT with the Las Campans du Pont 2.5-m telescope (+ WFCCD spectrograph): Inspection of the spectrum shows that 2008fw is a type-Ia supernova near maximum light. Comparison with a library of supernova spectra via the "Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024) gives excellent agreement with a number of normal type-Ia supernovae at ages between one week before and 3-4 days after maximum brightness. An expansion velocity of 9700 km/s is derived from the minimum of the Si II 635.5-nm absorption, when the NED redshift of 2563 km/s is assumed for the host galaxy (Koribalski et al. 2004, A.J. 128, 16).
