Global MHD simulation of flux transfer events at the high-latitude magnetopause observed by the cluster spacecraft and the SuperDARN radar system [PDF]
, 2008 A global magnetohydrodynamic numerical simulation is used to study the large-scale structure and formation location of flux transfer events (FTEs) in synergy with in situ spacecraft and ground-based observations. During the main period of interest on the

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 ...

A statistical study of magnetospheric electron density using the Cluster spacecraft [PDF]
Journal of Geophysical Research: Space Physics, 2016 Observations from the WHISPER (Waves of High frequency and Sounder for Probing of Electron density by Relaxation) instrument on board Cluster, for the interval spanning 2001–2012, are utilized to determine an empirical model describing the total electron

On the estimation of the current density in space plasmas: multi versus single-point techniques [PDF]
, 2017 Thanks to multi-spacecraft mission, it has recently been possible to directly estimate the current density in space plasmas, by using magnetic field time series from four satellites flying in a quasi perfect tetrahedron configuration. The technique developed, commonly called 'curlometer' permits a good estimation of the current density when the ...

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.

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

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 ...

Solitary potential structures observed in the magnetosheath by the Cluster spacecraft [PDF]
Nonlinear Processes in Geophysics, 2003 Abstract. Bipolar pulses of ~ 25-100 µs in duration have been observed in the wave electric field data obtained by the Wideband plasma wave instrument on the Cluster spacecraft in the dayside magnetosheath. These pulses are similar in almost all respects to those observed on several spacecraft over the last few years.
