The results of the spectroscopic study of the Ae Herbig star RR Tau are reported. The observations were carried out with a moderate resolution. In accordance with the presented data the Hα line exhibits a double-peaked emission profile. The blue component is weaker than or equal to the red one. Variations of the Hα equivalent width by a factor of 4–5 were found. The structure of this line also varies. On JD 2447148 a red absorption reversal of the Hα profile was observed. The Hβ spectral line exhibited both emission and absorption. On JD 2449664 the single-peak emission shifted to the short-wavelength range of the underlying absorption line and the red wing of the stellar line looked like a red-shifted absorption component of medium strength. The Hδ line was in absorption.
