Extract
A bright enigmatic supergiant, 89 Her (HD 163506; F2Ia, Mbol=-7m.5), exhibits the light variations (Percy et al. 1979, Fernie 1981, 1983) as well as the changes of radial velocities and structures of Balmer and sodium lines. Sargent and Osmer (1969) have given some evidences for the existence of expanding circumstellar envelope around 89 Her and have discovered 24 emission lines of neutral metals in its spectra.
