Cluster PEACE observations of electrons of spacecraft origin [PDF]

Annales Geophysicae, 2001
The two PEACE (Plasma Electron And Current Experiment) sensors on board each Cluster spacecraft sample the electron velocity distribution across the full 4<pi> solid angle and the energy range 0.7 eV to 26 keV with a time resolution of 4 s ...

Statistical Survey of the Terrestrial Bow Shock Observed by the Cluster Spacecraft [PDF]

Journal of Geophysical Research: Space Physics, 2019
The terrestrial bow shock provides us with a unique opportunity to extensively investigate properties of collisionless shocks using in situ measurements under a wide range of upstream conditions.

Detection of a plasmaspheric wind in the Earth's magnetosphere by the Cluster spacecraft [PDF]

Annales Geophysicae, 2013
. Plumes, forming at the plasmapause and released outwards, constitute a well-established mode for plasmaspheric material release to the Earth's magnetosphere. They are associated to active periods and the related electric field change.

Simulation of the Cluster-Spacecraft Floating Probe Potential [PDF]

IEEE Transactions on Plasma Science, 2006
In this paper, a numerical model of the Cluster-spacecraft electric potential has been developed and validated. This model provides a good fit to the plasma density as a function of spacecraft chassis potential relative to a Langmuir probe as recorded ...

Spacecraft potential control aboard Equator-S as a test for Cluster-II [PDF]

Annales Geophysicae, 1999
The payload of Equator-S was complemented by the potential control device (PCD) to stabilise the electric potential of the spacecraft with respect to the ambient plasma. Low potentials are essential for accurate measurements of the thermal plasma. The

Whistlers observed by the Cluster spacecraft outside the plasmasphere [PDF]

Journal of Geophysical Research: Space Physics, 2005
Lightning generated whistlers are ubiquitous within the plasmasphere at both high and low altitudes, and these waves propagate efficiently in both ducted and nonducted modes. On the other hand, in the magnetospheric region outside the plasmasphere, lightning‐generated whistlers are commonly observed at low altitudes (up to ∼6000 km) but only rarely at ...

Anisotropic Turbulent Spectra in the Terrestrial Magnetosheath as Seen by the Cluster Spacecraft [PDF]

Physical Review Letters, 2006
Here we report the first three-dimensional spatial spectrum of the low frequency magnetic turbulence obtained from the four Cluster spacecraft in the terrestrial magnetosheath close to the magnetopause. We show that the turbulence is compressible and dominated by mirror structures, its energy is injected at a large scale kp approximately 0.3 (l ...

Coordinated interhemispheric SuperDARN radar observations of the ionospheric response to flux transfer events observed by the Cluster spacecraft at the high-latitude magnetopause [PDF]

Annales Geophysicae, 2003
At 10:00 UT on 14 February 2001, the quartet of ESA Cluster spacecraft were approaching the Northern Hemisphere high-latitude magnetopause in the post-noon sector on an outbound trajectory. At this time, the interplanetary magnetic field incident

Active spacecraft potential control for Cluster – implementation and first results [PDF]

Annales Geophysicae, 2001
Electrostatic charging of a spacecraft modifies the distribution of electrons and ions before the particles enter the sensors mounted on the spacecraft body. The floating potential of magnetospheric satellites in sunlight very often reaches several

Detection of meteoroid hypervelocity impacts on the Cluster spacecraft: First results [PDF]

Journal of Geophysical Research: Space Physics, 2016
AbstractWe present the first study of dust impact events on one of the Earth‐orbiting Cluster satellites. The events were identified in the measurements of the wide band data (WBD) instrument on board the satellite operating in monopole configuration. Since 2009 the instrument is operating in this configuration due to the loss of three electric probes ...
