Abstract: The results of the investigation of line Hα in the spectrum of the spectral binary star HD 206267 have been presented. The observations were carried out at the Cassegrain focus of the 2-m telescope (Zeiss-2000) of N.Tusi Shamakhy Astrophysical Observatory (ShAO) of NAS of Azerbaijan, using echelle-spectrometer, during 2011–2014. The moving absorption components from red to violet direction in the core of the profile of line Hα, have been revealed. The appearance of discrete absorption components and their movement in the core of line Hα could be explained by the formation and movement referred to as Co-rotating Interaction Regions (CIR) in the envelope of the HD 206267.
