We use whistler waves observed close to the mag-netopause as an instrument to investigate the internal struc-ture of the magnetopause-magnetosheath boundary layer. Wefind that this region is characterized by tube-like structureswith dimensions less than or comparable with an ion iner-tial length in the direction perpendicular to the ambient mag-netic field. The tubes are revealed as they constitute regionswhere whistler waves are generated and propagate. We be-lieve that the region containing tube-like structures extendseveral Earth radii along the magnetopause in the boundarylayer. Within the presumed wave generating regions we findcurrent structures moving at the whistler wave group velocityin the same direction as the waves.
