Abstract
As it is well known, sunspots contain both vertical and horizontal strong magnetic fields. We are interested in the line-of-sight velocity structures in sunspots, with emphasis on penumbral motions. There are two types of regular motion of the solar plasma in the sunspot penumbra, namely the Evershed effect and oscillations. We were successful in the identification of a relation between some oscillatory modes of the line-of-sight velocity (8–10, 12–15, 20–30 min) and Evershed flows.
