Abstract

The results of spectral observations of the supergiant star HD21389 were presented. Variations of the spectral parameters and proles of the Hα line were discovered. It is supposed that variability of the proles, radial velocity and other parameters are connected each with other and also these changes may be a manifestation of complex motions in the atmosphere of HD 21389.
