Giant events in the 23rd solar cycle: Common and specific features
Struminsky, A. B.
Giant X-ray events (>X17) in the 23rd solar cycle (October 28 and November 4, 2003, and September 7, 2005) are considered, which were almost completely observed in hard X rays (>150 keV) from the INTEGRAL satellite and partly from the RHESSI satellite. These events are compared with two events completely observed from the RHESSI satellite (X…
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…
