Filippenko and Foley add that inspection of CCD spectra, obtained as above, shows that SN 2005aj (cf. IAUC 8488) is of type Ic. The O I 777.4-nm and Ca II near-infrared triplet absorption troughs are very strong. Prominent Na I D absorption produced by Galactic gas (0.17-nm equivalent width) and host-galaxy gas (0.11- nm equivalent width) are qualitatively consistent with the observed red continuum.
