Pulsed flows at the high-altitude cusp poleward boundary, and associated ionospheric convection and particle signatures, during a Cluster - FAST - SuperDARN- S?ndrestr?m conjunction under a southwest IMF

摘要

Particle and magnetic field observations during amagnetic conjunction Cluster 1-FAST-Søndrestrøm within the field of viewof SuperDARN radars on 21 January 2001allow us to draw a detailed, comprehensive and self-consistent picture atthree heights of signaturesassociated with transient reconnection under a steady south-westerlyIMF (clock angle ≈130°).Cluster 1 was outbound through the high altitude (~12R_E) exterior northern cusptailward of the bifurcation line (geomagnetic B_x
