Measurements of line-of-sight velocities in prominences

Measurements of line-of-sight velocities of quiescent and sunspot prominences on the limb made during the years 1966 and 1968 at Swedish Astrophysical Station in Anacapri, Italy are discussed. Several statistical properties of the velocity field, in particular its connection with close McMath plages are investigated. Results are interpreted in terms of oscillatory motion in prominences.
