Two‐dimensional observations of overshielding during a magnetic storm by the Super Dual Auroral Radar Network (SuperDARN) Hokkaido radar
[1] Two-dimensional observations of ionospheric plasma flows possibly caused by overshielding are reported for the first time. The observations were made by the midlatitude Super Dual Auroral RadarExpand

Numerical Simulation of the Ring Current: Review
Numerical simulation of the terrestrial ring current is reviewed. After mentioning ‘modules’ which are needed to be taken into consideration in a ring current simulation, we discuss growth and decayExpand

GPS phase scintillation associated with optical auroral emissions: First statistical results from the geographic South Pole
[1] Ionospheric irregularities affect the propagation of Global Navigation Satellite System (GNSS) signals, causing radio scintillation. Particle precipitation from the magnetosphere into theExpand

Fate of outflowing suprathermal oxygen ions that originate in the polar ionosphere
[1] We investigate the transport and ultimate fate of outflowing suprathermal O+ ions by kinetic means using a full-particle tracing scheme. We launched O+ ions in order to determine their finalExpand

Simultaneous ground-satellite optical observations of postnoon shock aurora in the Southern Hemisphere
[1] On 14 June 2005, a transient postnoon shock aurora, induced by an interplanetary (IP) shock, was observed simultaneously with the FUV imager onboard the IMAGE satellite and the all-sky imagerExpand
