Periodic substorm activity in the geomagnetic tail by C. Y Huang ( )
3 editions published in 1983 in English and held by 184 WorldCat member libraries worldwide
On 19 May 1978 an unusual series of events is observed with the Quadrispherical LEPEDEA on board the ISEE-1 satellite in the earth's geomagnetic tail. For 13 hours periodic of both bursts of both ions and electrons are seen in all the particle detectors on the spacecraft. On this day periodic activity is also seen on the ground, where multiple intesifications of the electrojets are observed. At the same time the latitudinal component of the interplanetary magnetic field shows a number of strong southward deflections. We conclude that an extended period of substorm activity is occurring, which causes repeated thinnings and recoveries of the plasma sheet. These are detected by ISEE, which is situated in the plasma sheet boundary layer, as periodic dropouts and reappearances of the plasma. Comparisons of the observations at ISEE with those at IMP-8, which for a time is engulfed by the plasma sheet, indicate that the activity is relatively localized in spatial extent. For this series of events it is clear that a global approach to magnetospheric dynamics, e.g., reconnection, is inappropriate. (Author)

The temporal evolution of a small auroral substorm as viewed from high altitudes with Dynamics Explorer 1 by J. D Craven ( Book )
2 editions published in 1985 in English and held by 72 WorldCat member libraries worldwide
"A small auroral substorm is investigated with auroral imaging photometers carried on the spacecraft Dynamics Explorer 1. Initial brightening along the auroral oval and the subsequent westward and poleward motions of intense, localized emission regions are associated with auroral surges. Following substorm onset, another region of less intense emissions is observed to develop at lower latitudes and adjacent to the bright region near local midnight. This second region expands towards the east. The bright zone of auroral emissions associated with the surges is interpreted as the signature of electron acceleration along magnetic field lines threading the boundary layer of the plasma sheet in the magnetotail. The more diffuse, less intense region is identified with eastward-drifting electrons injected into the plasma sheet and ring current following substorm onset. No rapid poleward motion of the discrete aurora is detected during substorm recovery."--NTRS abstract

On the distributions of plasmas and electric fields over the auroral zones and polar caps by Louis A Frank ( Book )
1 edition published in 1971 in English and held by 4 WorldCat member libraries worldwide
Simultaneous observations of DC electric fields and low-energy charged particles at low altitudes over the earth's auroral zones and polar caps were obtained with the satellite Injun 5. Several of the principal results for the evening and dawn local time sectors are summarized
Entry of low-energy solar protons into the earth's magnetotail by Nicolaos A Saflekos ( Book )
1 edition published in 1975 in English and held by 4 WorldCat member libraries worldwide
The access of low-energy solar protons (E sub p> 0.3 MeV) from the interplanetary medium into the earth's magnetotail was studied using observations obtained by Explorers 33, 34, and 35 over a 4.5 year period. Emphasis is on events whose intensity-time profiles exhibit sharply defined discontinuities observed by at least one of the three spacecraft in the interplanetary medium and another within the magnetotail

Drift of noninteracting charged particles in a simple geomagnetic field by M. A Schield ( Book )
1 edition published in 1969 in English and held by 4 WorldCat member libraries worldwide
The corotation of plasmas within the plasmasphere has been observed and the existence of a potential difference across the magnetosphere in the dawn-dusk meridian of several tens of kilovolts is consistent with various geophysical observations. The purpose of the paper is to solve analytically the drift motion of noninteracting charged particles, mirroring equatorially in a rotating magnetic dipole-field, across which is superimposed a uniform electric field

Low-energy proton (0.5 [less than or equal to] E [less than or equal to] 50 keV omnidirectional intensity contours in the earth's outer radiation zone at the magnetic equator by Louis A Frank ( Book )
1 edition published in 1969 in English and held by 3 WorldCat member libraries worldwide
Observations of low-energy proton intensities within seven selected energy bandpasses spanning the energy range 0.5 <E <50 keV are summarized in L-value versus time diagrams for the period 10 June through 23 July 1966. These contours of omnidirectional, differential proton intensities were calculated via measurements of the directional, differential spectrums of the proton intensities with a sensitive electrostatic analyzer array borne on the earth-satellite OGO 3 at mid- and low latitudes in the outer radiation zone and are normalized to a geomagnetic latitude 0 deg. (magnetic equator). These L-versus-time diagrams provide a compact, useful summary of these unique observations of proton intensities over L-values ranging from 3.0 to 12 and promote further insight into the morphological features of one of the most dynamically important components of magnetospheric plasma.
