R. Ellis, California Institute of Technology (CIT); M. Sullivan, University of Toronto; P. Nugent, Lawrence Berkeley National Laboratory; and A. Gal-Yam, CIT, report that a CCD spectrum (range 360-950 nm) of SN 2004Z (cf. IAUC 8290), obtained on Feb. 22 UT with the Keck-I 10-m reflector (+ LRIS), reveals it to be a relatively young type-II supernova, featuring a blue continuum with strong P-Cyg profiles of the hydrogen Balmer lines as well as He I (587.6 nm). The maximum velocity of H_alpha in SN 2004Z is approximately 10000 km/s.
