A. V. Filippenko and R. J. Foley, University of California, Berkeley; and T. Matheson, National Optical Astronomy Observatory, report that inspection of a CCD spectrogram (range 330-930 nm), obtained on Dec. 4 UT with the Keck I 10-m telescope (+ LRIS), shows that SN 2005kz is of type Ic, perhaps 1 week after maximum brightness, with a peculiar spectrum resembling those of SN 1998bw (Patat et al. 2001, Ap.J. 555, 900) and SN 2002ap (Foley et al. 2003, PASP 115, 1220). The Ca II near-infrared triplet has an unusually broad absorption trough, thoroughly blended with the O I 777.4-nm line.
