"The importance of a sign of the IMF BZ component for solar wind plasma entry into the magnetosphere was suggested about 40 years ago and later it was documented by experimental investigations. When IMF BZ is negative, subsolar reconnection fills the cusp with the magnetosheath plasma which partly precipitate to the ionosphere and partly is reflected and create a plasma mantle. During periods of a positive IMF BZ, the reconnection site moves tailward of the cusp. However, such situations are rather rare because BZ is often a minor IMF component. In spite of this, the structure of the cusp during periods of a small IMF BZ component is generally unknown; partly due to fully 3-D nature of interaction and partly due to a lack of experimental data. In the present paper, we are analyzing two-point observations of the cusp\u2013magnetosheath boundary during a prolonged interval of dawnward pointing IMF."@en . . "0273-1177" .
