R. Covarrubias, Observatories of the Carnegie Institution of Washington (OCIW) and Anglo Australian Observatory; and N. Morrell, OCIW and the Carnegie Supernova Project, report that a spectroscopic observation (range 400-1000 nm) of 2009as (cf. CBET 1717), obtained on Mar. 15.4 UT with the Magellan II Clay telescope (+ LDSS3) at Las Campanas Observatory, shows this to be a type-Ia supernova. Cross-correlation with a library of supernova spectra, using the "Supernova Identification" code (SNID; Blondin and Tonry, 2007, Ap.J. 666, 1024), gives a very good match with several normal type-Ia supernovae between 10 and 14 days after maximum. Adopting the NED recession velocity for the host galaxy of 6649 km/s (Theureau et al. 2007, A.Ap. 465, 71), the minimum of the Si II 635.5-nm absorption reveals an expansion velocity of approximately 11700 km/s.
