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 ...

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

The Double Star Plasma Electron and Current Experiment [PDF]

Annales Geophysicae, 2005
The Double Star Project is a collaboration between Chinese and European space agencies, in which two Chinese magnetospheric research spacecraft, carrying Chinese and European instruments, have been launched into equatorial (on 29 December 2003) and ...

Polar and Cluster observations of a dayside inverted-V during conjunction [PDF]

Annales Geophysicae, 2007
We investigate particle and fields data during a conjunction of the Polar and Cluster spacecraft. This conjunction occurs near the dayside cusp boundary layer when a dayside inverted-V was observed in the particle data of both satellites.

Cluster Multi-spacecraft Determination of AKR Angular Beaming [PDF]

, 2008
Simultaneous observations of AKR emission using the four-spacecraft Cluster array were used to make the first direct measurements of the angular beaming patterns of individual bursts. By comparing the spacecraft locations and AKR burst locations, the angular beaming pattern was found to be narrowly confined to a plane containing the magnetic field ...

Artificial spacecraft in hybrid simulations of the quasi-parallel Earth's bow shock: analysis of time series versus spatial profiles and a separation strategy for Cluster [PDF]

Annales Geophysicae, 1994
We construct artificial "software" spacecraft consisting of magnetometers and 3D thermal and energetic ion detectors. Four such spacecraft are "flown" through a 1D simulation of a quasi-parallel shock. We analyze the resulting time

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

First simultaneous observations of flux transfer events at the high-latitude magnetopause by the Cluster spacecraft and pulsed radar signatures in the conjugate ionosphere by the CUTLASS and EISCAT radars [PDF]

, 2001
Cluster magnetic field data are studied during an outbound pass through the post-noon high-latitude magnetopause region on 14 February 2001. The onset of several minute perturbations in the magnetospheric field was observed in conjunction with a ...

Correlation functions of small-scale fluctuations of the interplanetary magnetic field [PDF]

, 2010
The Interplanetary Magnetic Field shows complex spatial and temporal variations. Single spacecraft measurements reveal only a one dimensional section of this rich four dimensional phenomenon. Multi-point measurements of the four Cluster spacecraft provide a unique tool to study the spatiotemporal structure of the field. Using Cluster data we determined
