[en] Complete text of publication follows. High resolution plasma and magnetic field data are used to validate analytical models of nonlinear mirror waves dynamics. Relation between threshold of instability and ips/peaks structures is investigated. It is shown that only models that account for multiple plasma population can explain observed mirror waves structures.
[en] Complete text of publication follows. The presentation will review advances, obtained in the last couple years, in our understanding of the magnetopause, its boundary layer, their role, and the processes that occur there. Observational, modelling and theoretical works will be reviewed.
[en] Complete text of publication follows. Most electromagnetic radiation which is of interest to radio astronomy comes either from electrons rotating in magnetic fields or from conversion of the much slower electrostatic waves generated by various plasma processes. Here the concentration is on the second process, with special emphasis on the Langmuir waves generated in the foreshocks of planets and in type II and III solar bursts.
[en] Complete text of publication follows. Simultaneous global imaging from space has revealed that the aurora can be significantly different in the two hemispheres. In this paper we report examples of large intensity differences and/or asymmetries and discuss what processes that can produce these differences.
[en] Complete text of publication follows. Proposed empirical and theoretical regularities and patterns underlying the sunspot cycle record will be reviewed, with special emphasis on recent model-based prediction attempts for cycle 24 and on nonlinear vs. stochastic mechanisms for producing grand minima/maxima.
[en] Complete text of publication follows. Taylor states are magnetic field morphologies in a sphere or shell that obey Taylor's constraint, namely the vanishing of the azimuthal component of the Lorentz torque on every cylinder coaxial with the rotation axis of the Earth. We report on simple models of the internal magnetic field structure in a sphere and a spherical shell that are compatible with morphologies of the magnetic field at the core surface.
[en] Complete text of publication follows. For the aurora of 1808 Humboldt has been described the relation between it and magnetic disturbances. The importance of the auroras of 1808-1810 will be demonstrated in relation to Humboldt's observations.
[en] Complete text of publication follows. Several features of the solar north-south asymmetries are presented by using sunspot data of the Greenwich and Debrecen datasets. The solar cycles of the two hemispheres have certain phase shifts and differences in strength and these features exhibit a certain connection. These asymmetries may have some relevance to the solar dynamo. Possible terrestrial effects are also analysed.
