Counterelectrojet and interplanetary magnetic field

Journal of Geophysical Research: Space Physics, 1978
About a dozen counterelectrojet events both in the afternoon and in the morning hours were compared with interplanetary magnetic field data. It was noticed that in three to four cases there was an association between counterelectrojets and an excursion of Bz from southward to northward.

Magnetic fields in the interplanetary medium

Advances in Space Research, 1982
Interplanetary magnetic field lines are attached to the Sun at one end • and their form is determined primarily by the motions of the solar wind and by the rotation of the Sun. The solar wind, in effect, carries the magnetic field lines with it as it moves radially away from the Sun, while the Sun carries the base of each line along a circle as it ...

The Configuration of the Interplanetary Magnetic Field

1972
The idealized basic structure of the interplanetary magnetic field is the familiar spiral wound on a cone whose axis is the solar rotation axis. Variations in the radial velocity of the solar wind produce large scale variations in pitch; slight distortions are also produced by the non-radial component of the solar wind velocity.

Magnetic Fields in Interplanetary Space

Science, 1965
The brief period between the conception of the interplanetary magnetic field and conclusive proof of its existence has been an exciting one. Imaginative theoretical developments and careful experimental verification have both been essential to rapid progress.

Prediction of the interplanetary magnetic field strength

Journal of Geophysical Research: Space Physics, 1995
A new model of the coronal and interplanetary magnetic field can predict both the interplanetary magnetic field strength and its polarity from measurements of the photospheric magnetic field. The model includes the effects of the large‐scale horizontal electric currents flowing in the inner corona, of the warped heliospheric current sheet in the upper ...

Interplanetary Magnetic Field Dynamics

2001
The role of the IMF in the dynamics of solar wind interaction with the geomagnetosphere was proposed by Dungey in 1961. Early in-situ IMF measurements in the 60's confirmed the association of the magnitude and direction of the IMF with the Kp magnetic activity index.

Solar and Interplanetary Magnetic Field I. The General Magnetic Field

Publications of the Astronomical Society of Japan, 1956
Abstract It is proposed that a possible solar and interplanetary magnetic field may have been built up by the movement of conducting material, steadily emitted from the sun, through the solar original magnetic field. An unknown function S(φ) and two parameters N and n, in this theory, are necessary to account for the shape of of lines ...

Cosmic rays in the interplanetary magnetic fields

Icarus, 1968
Abstract The propagation of cosmic rays in the regular and random interplanetary magnetic fields transferred by the clouds of the interplanetary plasma is considered. The equation for the distribution function is obtained. This equation is discussed in the diffusion and drift approximations and explicit solutions for some particular cases are found ...

Interplanetary Magnetic Fields and Cosmic Rays

Physical Review, 1955
The existence in the region around the sun of a field-free cavity in the galactic magnetic field seems indicated by the low-energy cosmic rays that reach the earth from the sun. Such a cavity would be produced by the solar corpuscular emission. A mean radius of the order of 200 times the distance from the sun to the earth may be estimated for this ...

Interplanetary Magnetic Field and the Auroral Zones

Physical Review Letters, 1961
Abstract : It was found that a model with a southward interplanetary magnetic field leads to a natural explanation of the SD currents. Speculative aspects of the problem as they appear at this time are discussed. It should be remembered that this problem is amenable to revolutionary progress by observations from rockets or satellites which go out more ...
