Cluster multispacecraft observations at the high-latitude duskside magnetopause: implications for continuous and component magnetic reconnection
We report multispacecraft Cluster observations of magnetic reconnection at the high-latitude magnetopause/magnetospheric boundary layer (MP/BL) under mainly northward interplanetary magnetic field (IMF) conditions. The event we study is on 3 December 2001 when the Cluster spacecraft were skimming the high-latitude duskside MP/BL during a period of about four hours. The orbit and configuration o...
متن کاملReconstruction of two-dimensional magnetopause structures from Cluster observations: verification of method
A recently developed technique for reconstructing approximately two-dimensional (∂/∂z≈0), timestationary magnetic field structures in space is applied to two magnetopause traversals on the dawnside flank by the four Cluster spacecraft, when the spacecraft separation was about 2000 km. The method consists of solving the GradShafranov equation for magnetohydrostatic structures, using plasma and m...

متن کاملOptimal reconstruction of magnetopause structures from Cluster data
The Grad-Shafranov (GS) reconstruction technique, a single-spacecraft based data analysis method for recovering approximately two-dimensional (2-D) magnetohydrostatic plasma/field structures in space, is improved to become a multi-spacecraft technique that produces a single field map by ingesting data from all four Cluster spacecraft into the calculation. The plasma pressure, required for the t...
متن کاملMagnetic reconnection and cold plasma at the magnetopause
[1] We report on detailed observations by the four Cluster spacecraft of magnetic reconnection and a Flux Transfer Event (FTE) at the magnetopause. We detect cold (eV) plasma at the magnetopause with two independent methods. We show that the cold ions can be essential for the electric field normal to the current sheet in the separatrix region at the edge of the FTE and for the associated accele...
