M. Hamuy, Carnegie Observatories, reports spectroscopic observations (range 380-725 nm) of SN 2002jz made by M. Roth and N. Morrell on Dec. 27.22 UT with the Las Campanas Observatory Dupont 2.5-m telescope (+ Modular Spectrograph). The spectrum bears some resemblance to that of the type-Ic SN 1994I taken 10 days past maximum (Filippenko et al. 1995, Ap.J. 450, L11). Both supernovae show a strong Na I D 589.2-nm line exhibiting a P-Cyg profile and prominent blends of Fe II lines between 400 and 470 nm. However, SN 2002jz shows an evident absorption (possibly H-alpha) at 644 nm (rest wavelength) that is not present in SN 1994I, suggesting perhaps an intermediate IIb-type supernova. Na I D interstellar lines at the redshift of the host galaxy can be seen with an equivalent width of 0.1 nm, which suggests significant reddening by dust.
