Blondin, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, reports that a spectrum (range 350-740 nm) of 2008cz (cf. CBET 1402), obtained on June 10.17 UT by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova at 2-3 weeks past maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2008cz is most similar to the type-Ia supernova 1994D at 17 days past maximum light. Adopting a recession velocity of 10263 km/s for the host galaxy of 2008cz (Dale et al. 1997, A.J. 114, 455; via NED), the maximum absorption in the Si II line (rest 635.5 nm) is blueshifted by roughly 9500 km/s.
