| Abstract: | The correlation between the indices, characterizing the intensity of the symmetric (SYM) and asymmetric (ASY) parts of a magnetic disturbance during a magnetic storm, and the indices, reflecting the intensity of the eastward (AU) and westward (AL) electrojets in the auroral zone, are analyzed. The role of the magnetospheric-ionospheric current systems in the generation
of a geomagnetic disturbance asymmetry during the magnetic storm main and recovery phases has been assessed based on this
analysis.
