Cluster and Double Star multipoint observations of a plasma bubble
Zhang, T. L.; Dandouras, I.; Lucek, E. +14 more
Depleted flux tubes, or plasma bubbles, are one possible explanation of bursty bulk flows, which are transient high speed flows thought to be responsible for a large proportion of flux transport in the magnetotail. Here we report observations of one such plasma bubble, made by the four Cluster spacecraft and Double Star TC-2 around 14:00 UT on 21 …
Shape, size, velocity and field-aligned currents of dayside plasma injections: a multi-altitude study
Pitout, F.; Fazakerley, A. N.; Dunlop, M. W. +3 more
On 20 February 2005, Cluster in the outer magnetosphere and Double Star-2 (TC-2) at mid-altitude are situated in the vicinity of the northern cusp/mantle, with Cluster moving sunward and TC-2 anti-sunward. Their magnetic footprints come very close together at about 15:28 UT, over the common field-of-view of SuperDARN radars. Thanks to this conjunc…
Magnetosheath excursion and the relevant transport process at the magnetopause
Dandouras, I.; Rème, H.; Cao, J. B. +5 more
A large-amplitude excursion of the magnetosheath (MS) in quiet solar wind conditions on 17 March 2004 was recorded simultaneously by the Cluster and TC-1 spacecraft. During this period, the IMF Bz was entirely northward. The coherence between the bow shock motion and magnetopause (MP) motion is revealed and the excursion velocities of t…
Mirror waves and mode transition observed in the magnetosheath by Double Star TC-1
Zhang, T. L.; Wang, C.; Volwerk, M. +2 more
The Double Star TC-1 magnetosheath pass on 26 February 2004 is used to investigate magnetic field fluctuations. Strong compressional signatures which last for more than an hour have been found near the magnetopause behind a quasi-perpendicular bow shock. These compressional structures are most likely mirror mode waves. There is a clear wave transi…
