vo@fai.kzmassive-starswolf-rayet-starsspectroscopybv-photometryccd-photometryjohnson-photometryphotometrystellar-photometryvariable-stars This catalogue contains results of **photometric and spectral observations** of seven Galactic **Wolf–Rayet stars** of the **WC and WO sequences**, obtained in 2021–2022 at the *Fesenkov Astrophysical Institute (FAI), Kazakhstan*. The observing programme included moderately bright stars (mostly fainter than *V = 10m*) observed in **B**, **V**, and **Rc** photometric filters, as well as **medium-resolution spectra** for measuring absolute fluxes in prominent emission lines. For each object, the table provides: * identifiers (WR catalogue number, alternative name), * spectral subtype, * equatorial coordinates (J2000), * literature photometry (B_cat, V_cat) and reference codes, * date of observation and Julian Date (JD−2400000), * measured **B**, **V**, **Rc** magnitudes with their errors, * and absolute fluxes and equivalent widths for a set of emission lines, including **C III λ4650**, **He II λ4686**, **C IV λ5017**, **He II λ5411**, **He II + C IV λ6560**, **C III λ6744**, **C IV λ7065**, and **C II λ7234**.
