Photometric and spectral observations of 11 Wolf-Rayet stars of the WN sequence were made at the AFIF during 2021-2022. Estimates of the brightness of objects in BVRc filters and the absolute fluxes of radiation in emission lines in this group are obtained on the basis of these observations. Changes in the brightness over a range of 0m.1-0m.15 are recorded for the stars WR 120, WR 151, and WR 152 in the WR I stars. Changes in the emission fluxes are detected in the spectra of several objects: WR 120, WR 128, and WR 145.
