Scientific paper

Radial velocities are presented for 70 faint OB stars in Vela, Centaurus, Circinus, and Norma. The measurements were performed on image-tube spectra of dispersion 43 Å/mm obtained at Cerro Tololo Inter-American Observatory. The mean radial velocities of the stars belonging to the Centaurus OB1 and Norma OB1 associations indicate that they follow the galactic rotation. Stars in Vela and Circinus show deviations from pure rotation when compared to the mean rotation curve of the Galaxy at the corresponding longitudes.
