Scientific objectives
Improve our understanding of the relationship between optical and plasma velocity transients. Experimentally define two-dimentional plasma flow patterns (EISCAT/ESR/CUTLASS) around frequently observed cusp/cleft auroral transients. It is of particular interest to relate these ionospheric footprints to certain modes of solar wind - magnetosphere interaction. An important goal will be to unanbiguously identify the ionospheric footprint of the magnetospheric separatrix between open and closed field lines and to determine the plasma convection pattern at the "open closed boundary". The auroral signature of this boundary can be determined by combining ground based auroral observations and particle precipitation from polar satellites (DMSP, NOAA, POLAR, FAST).
