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.

The interplanetary magnetic field structure

Nature, 1976
The seasonal bias in the sector structure of the interplanetary magnetic field has led to the suggestion that the field in each hemisphere of the solar cavity has the same polarity as the average magnetic field at the corresponding solar pole, and that the surface which separates the two polarity regions is only slightly warped.

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.

On interplanetary electric and magnetic fields

Solar Physics, 1982
A kinematic model of the stationary electromagnetic fields in interplanetary space with finite conductivity is considered. The electrodynamic problem is solved for a medium with uniform conductivity and radial plasma outflow from a spherical source. Simple analytical formulae are obtained for electric and magnetic fields, currents and charges in the ...

Polar substorm and interplanetary magnetic field

Planetary and Space Science, 1971
Abstract By means of the IMP 3 magnetic data, a study is made on the relationships between the interplanetary magnetic field and the development of polar substorm. It is found that an explosive growth of the westward electrojet tends to appear after the interplanetary magnetic field has directed southward for 1–2 hr.

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.

Solar wind and interplanetary magnetic field

Reviews of Geophysics, 1967
A brief history is presented of some of our ideas regarding the solar wind. The basic physical principles of supersonic expansion are discussed. An analogy is drawn with the flow of an ideal gas through a rocket‐engine nozzle. Supersonic expansion of a stellar corona requires a stellar and coronal temperature lower than a specified maximum.

REGULATION OF THE INTERPLANETARY MAGNETIC FIELD

1992
In this study we use a recently developed technique for measuring the combined magnitudes of inward and outward (sunward and antisunward) pointing 2D magnetic flux in the ecliptic plane to examine (1) the long term variation of the amount of magnetic field open to interplanetary space and (2) the apparent rate at which coronal mass ejections (CMEs) may
