Spectra of newly discovered WC5, WC6, and WC7 stars. Spectra are dominated by C IV emission. According to the relative intensity of their O V and C iii lines, WR-C-05, WR-C-10, and WR-C-58 belong to the WC5 subclass, WR-C-47 to WC6, and all other stars to WC7. The dashed black lines indicate the zero intensity scale of each spectrum. The position of the telluric absorption bands is marked with the symbol ⊕.
