Radial velocities of H2 - H9 abd Ca II K lines on 27 high dispersion (0.27 nm/mm) spectrograms of the HgMn-star Alpha Andromedae were measured, While radial velocities of Balmer lines show no significant changes, radial velocities of Ca II K line vary in the limits from 5 to 13 km/s. A frequency analysis of the Ca II K RV values leads to two different frequencies of 27.86 and 35.20 c/d. Their superposition results is a 196 min beat-phenomenon period. Halfwidth of the calcium line varies in the way which could be explained by nonradial oscillations.
