T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm) of SN 2004as, obtained by P. Berlind on Mar. 13.30 UT with the Mt. Hopkins 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova a few days before maximum light. A narrow H_alpha emission line superposed on the spectrum of the supernova indicates a recession velocity of 9300 km/s for the host galaxy. Using this value, the supernova expansion velocity is about 14100 km/s for Si II (rest 635.5 nm).
