TL;DR: The Cluster Ion Spectrometry (CIS) experiment as discussed by the authors measured the full, three-dimensional ion distribution of the major magnetospheric ions (H+, He+, He++, and O+) from the thermal energies to about 40 keV/e.
Journal ArticleDOI
Multiple-spacecraft observation of a narrow transient plasma jet in the Earth's plasma sheet
V. A. Sergeev,J. A. Sauvaud,D. Popescu,R. A. Kovrazhkin,Kan Liou,Patrick T. Newell,Mitchell J. Brittnacher,George K. Parks,Rumi Nakamura,Toshifumi Mukai,Geoffrey D. Reeves +10 more
TL;DR: In this article, the authors used observations from five magnetospheric spacecraft in a fortuitous constellation to show that narrow transient plasma flow jets of considerable length formed in the tail can intrude into the inner magnetosphere and provide considerable contribution to the total plasma transport.
Journal ArticleDOI
On spatial and temporal structures in the cusp
Karlheinz Trattner,S. A. Fuselier,W. K. Peterson,J. A. Sauvaud,H. Stenuit,N. Dubouloz,R. A. Kovrazhkin +6 more
TL;DR: In this paper, the authors identify a series of magnetic conjunctions and close encounters of polar-orbiting satellites to investigate cusp features including flux variations and sudden energy changes of cusp precipitating ions.
Journal ArticleDOI
Precipitation of fast ion beams from the plasma sheet boundary layer
TL;DR: In this article, a model of precipitated fluxes from the PSBL and CPS is presented, showing the important role of the VDIS auroral region medium for complicated and energetically significant processes occurring in different regions of the distant magnetotail.
Journal ArticleDOI
Statistic study of magnetosphere response to magnetic clouds: INTERBALL multi-satellite observations
Yu. I. Yermolaev,G. N. Zastenker,N. L. Borodkova,R. A. Kovrazhkin,N. S. Nikolaeva,M. N. Nozdrachev,S.P. Saving,A. Skalsky,Lev Zelenyi,Zdenek Nemecek,Jana Safrankova,J. A. Sauvaud +11 more
TL;DR: Several unusual features related to the interaction of magnetic clouds with the Earth's magnetosphere as observed on the INTERBALL satellites during 1995-1997 are discussed in this article, where the main cause of magnetospheric disturbances is high pressure pulses on leading and trailing edges of clouds.
