Journal ArticleDOI
Cluster observations of an intense normal component of the electric field at a thin reconnecting current sheet in the tail and its role in the shock-like acceleration of the ion fluid into the separatrix region
John R. Wygant,Cynthia A Cattell,Robert L. Lysak,Yan Song,J. Dombeck,J. P. McFadden,F. S. Mozer,C. W. Carlson,George K. Parks,E. A. Lucek,André Balogh,Mats André,H. Rème,Michael Hesse,C. G. Mouikis +14 more
TL;DR: In this article, measurements from the Cluster spacecraft of electric fields, magnetic fields, and ions are used to study the structure and dynamics of the reconnection region in the tail at distances of ∼18 RE near 22.4 MLT on 1 October 2001.
Journal ArticleDOI

Tai Phan,Harald U. Frey,S. Frey,Laura Peticolas,S. A. Fuselier,C. W. Carlson,H. Rème,J. M. Bosqued,André Balogh,M. W. Dunlop,L. M. Kistler,C. G. Mouikis,Iannis Dandouras,J. A. Sauvaud,Stephen B. Mende,J. P. McFadden,George K. Parks,Eberhard Moebius,B. Klecker,G. Paschmann,Masaki Fujimoto,S. M. Petrinec,Maria Federica Marcucci,A. Korth,Rickard Lundin +24 more
TL;DR: In this paper, the Tsyganenko-01 magnetic field model with enhanced solar wind pressure was used to map the magnetic-shear high-latitude magnetopause (MP) location to the vicinity of the IMAGE proton spot.
Journal ArticleDOI
Contribution of nonadiabatic ions to the cross-tail current in an O+ dominated thin current sheet
L. M. Kistler,C. G. Mouikis,Eberhard Möbius,B. Klecker,J. A. Sauvaud,H. Rème,A. Korth,Maria Federica Marcucci,Rickard Lundin,George K. Parks,André Balogh +10 more
TL;DR: In this paper, the O+ dominated thin current sheet is observed to stream from dawn to dusk across the tail, as predicted for nonadiabatic ions by Speiser (1965), and the current contribution from these ions is calculated and found that they carry about 5-10% of the cross-tail current.
Journal ArticleDOI
Energy deposition by Alfvén waves into the dayside auroral oval: Cluster and FAST observations
C. C. Chaston,Laura Peticolas,C. W. Carlson,J. P. McFadden,F. S. Mozer,Mark Q. Wilber,George K. Parks,A. J. Hull,Robert E. Ergun,Robert J. Strangeway,Mats André,Yu. V. Khotyaintsev,M. L. Goldstein,Mario H. Acuña,Eric J. Lund,H. Rème,I. Dandouras,Andrew Fazakerley,André Balogh +18 more
TL;DR: In this paper, in situ observations from the Cluster and FAST spacecraft showed the deposition of energy into the auroral ionosphere from broadband ULF waves in the cusp and low-latitude boundary layer.
Journal ArticleDOI
Kelvin‐Helmholtz waves under southward interplanetary magnetic field
K.-J. Hwang,K.-J. Hwang,Masha Kuznetsova,Fouad Sahraoui,M. L. Goldstein,Ensang Lee,George K. Parks +6 more
TL;DR: In this paper, the first in situ observation of nonlinearly developed Kelvin-Helmholtz wave (KHW) during southward interplanetary magnetic field (IMF) was presented.
