J. M. Silverman, M. T. Kandrashoff, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 340-1000 nm), obtained on Oct. 12 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, shows that SN 2009js is a type-II supernova; cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that it is most similar to the type-IIP supernova 2005cs about two days after maximum brightness. After removal of the host-galaxy recession velocity of 1507 km/s (Rhee et al. 1996, A.Ap. Suppl. 115, 407), the H-alpha absorption (which is greatly dominated by the emission component) is found to be blueshifted by about 7200 km/s.
