Abstract
The temporal and spatial properties of small-amplitude oscillations have been studied using spectral observations of motions in solar filaments carried out at the Sayan Solar Observatory (Institute of Solar-Terrestrial Physics, Russian Academy of Sciences). Oscillations with different periods and spatial scales exist simultaneously in filaments. Swaying motions of filaments in the plane of the sky have been detected. The character of these oscillatory motions is compared with oscillations in the Doppler velocity at the same filament sites.
