Large-amplitude morning Pc5 magnetic pulsations during the main phase of intense magnetic storm were registered at magnetic stations of 190-200° magnetic meridians on January 21-22, 2005. Magnetic pulsations in the Pc5 frequency range observed at the GOES 10, 12 satellites in the noon and evening sectors exhibited a high degree of magnetic compessibility. A Los Alamos particle detector on board geostationary satellite observed the occurrence of energetic particle flux oscillations in the Pc5 band. The Pc5 pulsations were followed with the VLF-emission and riometer absorption modulation with the same period. The regions of maximal amplitude of Pc5 geomagnetic pulsations and deep modulation of riometer absorptions shifted to high latitudes in the same way. Significant and long-lasting compression of magnetosphere led, probably, to moderate pitch-angle diffusion of particle into the loss cone even at the middle latitudes. Analysis of coordinated data allowed us to suggest that a modulation effects of precipitating particles are caused by a compressional waves.

The 20.11.03 super-storm is described on the basis of the quantitative estimations of input and output parameters of the magnetospheric disturbance energetics. Two input parameters are ε'- Poynting flux from solar wind into the magnetosphere, and the polar cap potential drop Upc. The output parameters (indicators the magnetospheric responses) are the total power of the magnetospheric disturbance (Qt), and the powers consumed in the ionosphere (Qi) and in the ring current (Qdr). Different modes of the magnetosphere disturbances are shortly described: substorms, driven mode, Null Events by Lyons et. al., saturation of the ionosphere, and responses to a strong s. w. pressure pulses. The problem of the substorms-storm relationship is also addressed.

In the accompanying Papers 1 and 2 was fulfilled timing of the 20.11.05 super-storm. Were detected 4 various types of the magnetospheric disturbances observable at southward IMF, and presented a new model of the field-aligned currents density spatial distribution in the polar ionosphere. In this paper are described the ionospheric convection systems, characteristic for the above various types. Are mentioned the mesoscale spatial inhomogeneities, which are observed more or less regularly but have not been mentioned in the past literature.

Spatial distribution in the polar ionosphere of field-aligned currents density is studied by using data of the events on 20.11.03. Observable distributions are described in terms of three Regions of Iijima and Potemra, with taken into account in each Region of three types of spatial inhomogeneities. These inhomogeneitie were overlooked earlier. Dynamics of classical substorm current wedge SCW1, and the "current wedges" SCW2 and SCW3, both creating a polarization and amplification of the westward auroral electrojet, are described.

In the present study we investigate the undulations at the equatorial boundary of diffuse aurora and their relationship to the development of magnetic and auroral substorms and excitation of Pc5 magnetic pulsation on January 14, 1999. The observed undulations had wave-length of ~200-300 km and amplitude of ~50-250 km and they propagated westward with the velocity of ~0,7 km/s. It is found that the undulations began ~40 min after the substorm onset and lasted for ~80 min, all the way to the end of the substorm. During both active and recovery phases of the substorm the undulations were accompanied by the enhancement of the DP2 equivalent current system and by the formation of WTS. Concurrently with undulations, there were observed Pc5 magnetic pulsations of an oscillation period roughly equal to the ratio of the undulation wavelength to their propagation velocity. Observations are interpreted in terms of the shear/ballooning instability excitation near the plasmapause and subsequent generation of drift hydromagnetic waves.

The spatial-temporal distribution of westward electrojets in the northern hemisphere has been investigated using geomagnetic ground observation data for November 9-10, 2004 geomagnetic storm. It is shown that the location of the maximum westward electrojet depends on the IMF orientation. It is in the evening or morning sector when Bγ0. With the increase of positive IMF Bγ, the region of intensity maximum shifts to morning hours. Thus, the azimuthal IMF component not only controls the pattern of magnetospheric convection, but also affects the longitudinal location of the westward electrojet pattern during the magnetic storm.
