An index, denoted by AE, is derived as a measure of global electrojet activity. The basic data
used are 2.5‐minute readings of the H trace in the standard magnetograms from seven …

This textbook was developed to provide seniors and first-year graduate students in physical
sciences with a general knowledge of electrodynamic phenomena in space. Since the …

This review will not merely be a précis of the literature in this field though a partial survey is
attempted. A critical stand will be taken and a point of view put forward. Experiments to test …

Extensive measurements of the magnetic field of the earth at distances greater than
approximately 7Re (earth radii) have been performed by the Imp 1 satellite. These magnetic …

The Explorer 12 measurements of the magnetic field outside the magnetosphere are
compared with ground magnetograms from arctic observatories. Results indicate that an …

This paper reviews present understanding of the internal structure of the thin boundary layer,
termed the magnetopause, that separates the distorted geomagnetic field in the …

Individual particle trajectories are determined analytically and numerically in two possible
configurations of electric and magnetic fields in the geomagnetic tail. The models are based …

A hot, suprathermal population of electrons is often present near the Earth's bow shock. The
overall morphology of this hot population as observed with the Los Alamos/Garching fast …

The azimuthal propagation of solar protons with kinetic energies in the range∼ 10 to∼ 30
Mev is investigated by using observations made in the period December 1967 through …

The Explorer 33 satellite was launched July 1, 1966 and was injected into a highly elliptical
earth orbit. The Goddard Space Flight Center magnetic field experiment onboard the …
