The Goldberg-Unno method is analysed. Accounting for the instrumental profile correction reduces the derived microturbulent velocities only slightly. A similar effect may be caused by an unresolved macroturbulence. The method of accounting for the damping effect is considered. The correction for the

We have examined whether the motion field in the photosphere in the range of optical depths 0.25 < z0< 0.6 is dominated by thermal convection or by vibrations. The observed asymmetries of infrared Fraunhofer lines indicate the presence of motions, and the fact that the asymmetry is zero for lines of

Motions in an old center of activity have been studied at the limb with the use of timeresolved Ha spectra. The observations were made at intervals of 5 seconds over a period of 88 hour of good seeing at Sacramento Peak Observatory. Objects in this region have larger line-of-sight velocities than h
