Variations in Ion-Component Pressure during Dipolarization in the Near-Earth Magnetotail Plasma Sheet
Malykhin, A. Yu.; Grigorenko, E. E.; Kronberg, E. A. +1 more
The dynamics of fluxes of thermal and suprathermal H+ and O+ ions and the pressure variations of these components during 11 events of magnetic field dipolarization in the plasma sheet of the geomagnetic tail are analyzed based on Cluster satellite observations. It was found that the energy of H+ and O+ i…
The Effect of the Betatron Mechanism on the Dynamics of Superthermal Electron Fluxes within Dipolizations in the Magnetotail
Daly, P. W.; Malykhin, A. Yu.; Grigorenko, E. E. +1 more
The dynamics of high-energy electron fluxes (with energies over 40 keV) is analyzed in 13 events of magnetic field dipolization observed by the Cluster satellites in the near-tail of the Earth magnetosphere. In all of the events, the observed energetic electron fluxes are enhanced simultaneously with initial dipolization. Good correlation (correla…
Some aspects of modelling the high-latitude ionospheric convection from Cluster/Edi data
Haaland, S. E.; Förster, M.; Gromova, L. I. +3 more
Measurements onboard Cluster satellites are briefly described, which form the base for determining the intensity and direction of the electric field in the magnetosphere. The aim of this paper is to describe (1) the methodology of calculating the potential distribution at the ionospheric level and the results of constructing spatiotemporal convect…
Magnetic turbulence in the cusp region: 3D spectra and vortex cascades
Romanov, S. A.
Cluster satellite measurements that were carried out in the region of the altitudinal cusp in the Earth's magnetosphere and adjacent regions were processed to yield the dynamic pattern of the 3D spectra of magnetic field oscillations in the space of wave vectors, with wave numbers ranging from 0.002 to 0.5 rad/km. The anisotropic properties of spa…
On the possibility of coupling satellite and ground-based optical measurements in the region of pulsating auroras
Safargaleev, V. V.; Shibaeva, D. N.; Sergienko, T. I. +1 more
The possibility of comparing in detail CLUSTER satellite data with data on pulsating spots registered with a TV camera at the Lovozero Observatory when the satellite crossed the magnetospheric region related to the camera's field of view is discussed. The satellite ionospheric projections were calculated using the T89, T96, and T01 models. It was …
