Abstract (from CDS):
T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm) of SN 2003iz, obtained by P. Berlind on Oct. 23.28 UT with the Mt. Hopkins 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova after maximum. Adopting the NED recession velocity of 14453 km/s for the host galaxy, the supernova expansion velocity is 12000 km/s for Si II (rest 635.5 nm). The spectral-feature age of the supernova is 6 ± 2 days after maximum light.
