PROF. H. A. WILSON is best known for his experimental researches, but this book shows that he is also able to give clear expositions of the more theoretical aspects of modern physics. As he has
The ionospheric signatures of rapid subauroral ion drifts
Subauroral ion drifts (SAID) are latitudinally narrow regions of rapid westward ion drift located in the evening sector and centered on the equatorward edge of the diffuse aurora. Observations of
A proposed production model of rapid subauroral ion drifts and their relationship to substorm evolution
Multisatellite data are used to examine the temporal relationship between Subauroral Ion Drifts (SAID) and the phases of an auroral substorm. Utilizing images of auroral luminosities taken by the
Multisatellite observations of rapid subauroral ion drifts (SAID)
We present the first conjugate observations of subauroral ion drifts (SAID) in the magnetosphere (∼9000 km altitude) and ionosphere and coincident measurements by four ionospheric satellites. The
Electrodynamic parameters in the nighttime sector during auroral substorms
The characteristics of the large-scale electrodynamic parameters, field-aligned currents (FACs), electric fields, and electron precipitation, which are associated with auroral substorm events in the
Effect of solar wind pressure pulses on the size and strength of the auroral oval
[1] It has recently been found that solar wind dynamic pressure changes can dramatically affect the precipitation of magnetospheric particles on the high-latitude ionosphere. We have examined the
Characteristics of spacecraft charging in low Earth orbit
[1] It has been found that the DMSP spacecraft at 840 km can charge to very large negative voltages (up to −2000 V) when encountering intense precipitating electron events (auroral arcs). We present
Storm time distributions of diffuse auroral electron energy and X-ray flux : Comparison of drift-loss simulations with observations
[1] We investigate the spatial structure of the electron diffuse aurora during the 19 October 1998 storm by comparing drift-loss simulations with precipitating particle data and auroral images.
Magnetospheric reconnection driven by solar wind pressure fronts
Abstract. Recent work has shown that solar wind dynamic pressure changes can have a dramatic effect on the particle precipitation in the high-latitude ionosphere. It has also been noted that the
Enhanced solar wind geoeffectiveness after a sudden increase in dynamic pressure during southward IMF orientation
[1] It is well known that a persistent southward Interplanetary Magnetic Field (IMF) produces increased geomagnetic activity. It has recently been shown that a sudden increase in solar wind pressure
