Magnetosphere response to the 2005 and 2006 extreme solar events as observed by the Cluster and Double Star spacecraft
Cao, Jinbin; Escoubet, Philippe; Rème, Henri +1 more
The four identical Cluster spacecraft, launched in 2000, orbit the Earth in a tetrahedral configuration and on a highly eccentric polar orbit (4-19.6 RE). This allows the crossing of critical layers that develop as a result of the interaction between the solar wind and the Earth’s magnetosphere. Since 2004 the Chinese Double Star TC-1 a…
Wave emissions at half electron gyroharmonics in the equatorial plasmasphere region: CLUSTER observations and statistics

Simultaneous observations of the plasma density on the same field line by the CPMN ground magnetometers and the Cluster satellites

Cluster observations of earthward propagating plasmoid and flux ropes in the near-tail during the course of a substorm event
Tang, C. L.; Lu, L.; Li, Z. Y.
We analyze the magnetic structures in the near-tail at XGSM = -17.5 RE on September 19, 2003 by Cluster. During the course of a substorm event, the earthward propagating plasmoid and flux ropes in the near-tail are observed. The earthward propagating plasmoid is associated with the bipolar Bz and By signatures. The two flux ropes are embedded with…
Broadband electrostatic noise and low-frequency waves in the Earth’s magnetosphere
Lakhina, G. S.; Singh, S. V.; Reddy, R. V.
Broadband electrostatic noise (BEN) is commonly observed in different regions of the Earth's magnetosphere, eg., auroral region, plasma sheet boundary layer, etc. The frequency of these BENs lies in the range from lower hybrid to the local electron plasma frequency and sometimes even higher. Spacecraft observations suggest that the high and low-fr…
HF wave activity in the low and middle-altitude polar cusp
Pitout, F.; Reme, H.; Trotignon, J. -G. +3 more
We reported the results of our investigations of wave activity in high-frequency range performed on board CLUSTER spacecraft in the middle-altitude cusp region, around 5 RE during August and September 2002. Our analysis was mainly based on the registration gathered by the WHISPER instrument (Waves of HIgh frequency and Sounder for Probi…
Plan management system for space science mission systems
Chaizy, P. A.; Dimbylow, T. G.; Hapgood, M. A. +1 more
The number and complexity of systems that control Space Science Missions continues to increase. As a result, it is desirable to improve the efficiency of these systems and, in particular, their performance and their productivity. In this paper, we set out a strategy to achieve this goal. In order to talk about improving the Performance and Product…
Cluster observations showing the indication of the formation of a modified-two-stream instability in the geomagnetic tail
Daly, P. W.; Erkaev, N. V.; Lui, A. T. Y. +4 more
This study presents several observations of the Cluster spacecraft on September 24, 2003 around 15:10 UT, which show necessary prerequisites and consequences for the formation of the so-called modified-two-stream instability (MTSI). Theoretical studies suggest that the plasma is MTSI unstable if (1) a relative drift of electrons and ions is presen…
Dynamics of the plasma sheet in the magnetotail: Interrelation of turbulent flows and thin current sheet structures
Domrin, V. I.; Kropotkin, A. P.
Dynamics of the magnetotail involves elementary processes of magnetic field merging (reconnection layer formation) occurring on medium spatial scales. Every such process features two different stages, a fast one and a subsequent slower one. The corresponding short time scale T1 is associated with disturbances propagating in the tail lob…
