The flapping motion of the magnetotail current sheet has a valuable contribution to magnetosphere dynamics. We have investigated features of flapping motions involving single- and multi-spacecraft methods using MMS and Cluster measurements. Velocities of dawn-dusk propagation of these motions and their types have been determined using Harris current sheet model and minimum variance analysis of the magnetic field. Dispersion features of such wavy motions using the phase differencing technique were explored.             

This work was carried out in accordance with the Target Comprehensive Program of the SRI NASU and SSAU in plasma physics with the support of grant no. 97742 of the Volkswagen Foundation (VW-Stiftung).
