Abstract

The β CMa star σ Scorpii has been observed spectroscopically along two cycles. It has been found that absorption lines representing different depths in the atmosphere (excluding the transition region) yield different radial velocity curves; the amplitudes decrease and the γ's become more negative in the outermost layers. Ca II λ3933 Å has a chromospheric component.
