A case study of low-frequency waves at the magnetopause
Dandouras, I.; Belmont, G.; Lucek, E. +10 more
We present the study of one of the first magnetopause crossings observed by the four Cluster spacecraft simultaneously, on 10 December 2000. Although the delays between the crossings are very short, the features of the boundary appear quite different as seen by the different spacecraft, strongly suggesting the presence of a local curvature of the …
Coordinated ground-based, low altitude satellite and Cluster observations on global and local scales during a transient post-noon sector excursion of the magnetospheric cusp
Orsini, S.; Pitout, F.; Balogh, A. +56 more
On 14 January 2001, the four Cluster spacecraft passed through the northern magnetospheric mantle in close conjunction to the EISCAT Svalbard Radar (ESR) and approached the post-noon dayside magnetopause over Green-land between 13:00 and 14:00 UT. During that interval, a sudden reorganisation of the high-latitude dayside convection pattern occurre…
First Cluster results of the magnetic field structure of the mid- and high-altitude cusps
Balogh, A.; Dunlop, M. W.; Cargill, P. J. +1 more
Magnetic field measurements from the four Cluster spacecraft from the mid- and high-altitude cusp are presented. Cluster underwent two encounters with the mid-altitude cusp during its commissioning phase (24 August 2000). Evidence for field-aligned currents (FACs) was seen in the data from all three operating spacecraft from northern and southern …
Ground-based and satellite observations of high-latitude auroral activity in the dusk sector of the auroral oval
Janhunen, P.; Orsini, S.; André, M. +18 more
On 7 December 2000, during 13:30-15:30 UT the MIRACLE all-sky camera at Ny Ålesund observed auroras at high-latitudes (MLAT ~ 76) simultaneously when the Cluster spacecraft were skimming the magnetopause in the same MLT sector (at ~ 16:00-18:00 MLT). The location of the auroras (near the ionospheric convection reversal boundary) and the clear corr…
Four point measurements of electrons using PEACE in the high-altitude cusp
Coates, A. J.; Wilson, R. J.; Owen, C. J. +8 more
We present examples of electron measurements from the PEACE instruments on the Cluster spacecraft in the high-latitude, high-altitude region of the Earth's magnetosphere. Using electron density and energy spectra measurements, we examine two cases where the orbit of the Cluster tetrahedron is outbound over the northern hemisphere, in the afternoon…
Preliminary two-point observations of the mid-altitude cusp by Cluster PEACE and FGM
Coates, A. J.; Wilson, R. J.; Fazakerley, A. N. +8 more
On 1 October 2000, Cluster spacecraft Samba (Cluster 3) and Tango (Cluster 4) made an outbound crossing of the northern mid-altitude (4.7 RE) cusp region, moving roughly parallel to the noon meridian. We present preliminary observations from this interval made by the PEACE and FGM instruments. The interplanetary magnetic field at the magnetopause …
