Energetic electron response to ULF waves induced by interplanetary shocks in the outer radiation belt
Zong, Q. -G.; Daly, P. W.; Baker, D. N. +7 more
Strong interplanetary shock interactions with the Earth's magnetosphere have great impacts on energetic particle dynamics in the magnetosphere. An interplanetary shock on 7 November 2004 (with the maximum solar wind dynamic pressure of ∼70 nPa) was observed by the Cluster constellation to induce significant ULF waves in the plasmasphere boundary, …
Energetic ion dynamics of the inner magnetosphere revealed in coordinated Cluster-Double Star observations
Cao, Jinbin; Dandouras, Iannis; Vallat, Claire
Since early 2004 the Chinese spacecraft Tan Ce 1 (TC-1), first component of the Double Star (DSP) mission, has been on an equatorial elliptical orbit (13.4 R E apogee), allowing the study of the dynamics of the Earth's magnetosphere in conjunction with the four European Cluster spacecraft (19.6 R E apogee). The Cluster an…
Simultaneous observations of flux transfer events by THEMIS, Cluster, Double Star, and SuperDARN: Acceleration of FTEs
Dandouras, I.; Fazakerley, A. N.; Milan, S. E. +3 more
We present simultaneous observations of flux transfer events (FTEs) made by the THEMIS and Cluster spacecraft on 3 May 2007, along with supporting observations of fast flows in the dayside ionosphere observed by the SuperDARN radar network. The THEMIS spacecraft were in a string-of-pearls formation approximately 20,000 km long and crossed the post…
Convective bursty flows in the near-Earth magnetotail inside 13 RE
Dunlop, M. W.; Baumjohann, W.; Carr, C. +8 more
With the 4-s resolution data of the magnetometer and the ion plasma analyzer on Double Star TC-1 from June to November of each year during the period of 2004-2006, we statistically analyzed the occurrence rate of both convective and field-aligned bursty flows (FABFs). In the region -13 RE < X < -9 RE, |Y| < 10 R…
Deformation and evolution of solar wind discontinuities through their interactions with the Earth's bow shock
Dandouras, I.; Nakamura, R.; Lucek, E. A. +13 more
The present study examines the interaction of solar wind discontinuities with the Earth's bow shock, using multipoint observations in the magnetosheath by Time History of Events and Macroscale Interactions During Substorms (THEMIS), Cluster, and Double Star TC1. We focus on the deformation and evolution of two discontinuities observed on 21 June 2…
