Magnetosphere cusp
WebJul 12, 2003 · The scientific objectives of the Cluster mission are to study the small-scale structures and the turbulence in the key regions of the magnetosphere. Such regions are: the solar wind, the bow shock, the magnetopause, the polar cusp and the magnetotail. In addition the temporal variations of structures observed in the auroral zone mid-altitude ... Webplasma into the magnetosphere [e.g., Reiff et al., 1977; Marklund et al., 1990]. However, the definition of the cusp used by MHD simulation [Siscoe et al., 2005] is "a weakening of the magnetic field owing to a pool of magnetosheath plasma within the magnetosphere - since the current is the plasma’s diamagnetic current

WebCusp structures can be described as spatial features observed by satellites crossing into spatially separated flux tubes. Cusp structures can also be observed as poleward-traveling (temporal) features within the same convection cell, most probably caused by variations in the reconnection rate at the magnetopause.
