The investigation of the magnetospheric polar cusps was one of the main objectives of the
Cluster mission. The four satellites have crossed those regions numerous times over the …

An understanding of the transport of solar wind plasma into and throughout the terrestrial
magnetosphere is crucial to space science and space weather. For non-active periods, there …

After 12 years of operations, the Cluster mission continues to successfully fulfil its scientific
objectives. The main goal of the Cluster mission, comprised of four identical spacecraft, is to …

On 28 February 2004 the configuration of the Cluster and Double Star TC1 satellites
facilitated a simultaneous study of plasma properties inside the low‐latitude boundary layer …

We report on a multispacecraft cusp observation lasting more than 100 min. We determine
the cusp boundary motion and reveal the effect on the cusp size of the interplanetary …

We present a case study of inverse ion cyclotron damping taking place in the northern
terrestrial magnetospheric cusp, exciting waves at the ion cyclotron frequency and its …

In recent years, a large number of papers have reported the response of the cusp to solar
wind variations under conditions of northward or southward Interplanetary Magnetic Field …

We have studied the stability of the electrostatic electron cyclotron wave in a plasma
composed of hydrogen, oxygen and electrons. To conform to satellite observations in the …

Résumé L'ionosphère est une région clé de l'environnement spatial terrestre où s' effectue
l'essentiel de la dissipation d'énergie issue du couplage avec la magnétosphère et le vent …

Observations made by Polar of ion-electron bursts on the dawn side of the polar cap are
presented. They occurred when conditions external to the magnetosphere corresponded to …
