Interplanetary magnetic‐field variations and substorm activity

, 1972
A fine time-scale study of interplanetary magnetic-field (IMF) variations and auroral-zone magnetograms during active (11 days of September, 1966, when auroral zone balloon X rays were available) and moderately active (October, 1965) days show that the ...

The collimation of cosmic rays by the interplanetary magnetic field.

, 1966
The Pioneer 6 spacecraft was instrumented to provide detailed information on the magnetic field, plasma, and energetic particles pervading interplanetary space.

Influence of interplanetary magnetic field and plasma on geomagnetic activity during quiet-sun conditions

, 1967
Observations by the IMP 1 satellite of the interplanetary magnetic field and plasma have been compared with the 3-hour geomagnetic activity index Kp. The average Kp is approximately a linear function of the interplanetary field magnitude B in gammas . It

Response of the geomagnetic activity index Kp to the interplanetary magnetic field

, 1967
: Interplanetary magnetic field observations with IMP-3 during eight solar rotations in the latter half of 1965 have been compared with the 3-hour Kp index. The results are consistent with those obtained with IMP-1 from three solar rotations in winter of

Effect of oblique interplanetary magnetic field on shape and behavior of the magnetosphere

, 1964
The oblique angle made by the spiral interplanetary magnetic field with the radially expanding solar wind is shown to result in an easterly deflection of the solar wind as it traverses the standing hydromagnetic shock wave a few earth radii upstream of ...

4.3.6 Interplanetary particles and magnetic fields

2009
More than five decades of active research with various spaceprobes cruising through the inner and outer heliosphere resulted in a wealth of measurements of solar wind parameters throughout the heliosphere [90S, 01N, 03N1]. The Helios probes collected data in the distance range between 0.29 AU and 1 AU for more than 12 years [b, c].

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.

Distributions of the interplanetary magnetic field revisited

Journal of Geophysical Research: Space Physics, 1994
The adequacy of the power spectrum to characterize the variations of a parameter depends on whether or not the parameter has a Gaussian distribution. We here perform very simple tests of Gaussianity on the distributions of the magnitudes of the interplanetary magnetic field, and on the distributions of the components; that is, we find the first four ...

The cosmic-ray flare effect: 3. Deductions regarding the interplanetary magnetic field

, 1962
The observations of cosmic-ray flare effects made at sea level are used to investigate the magnetic fields within the inner solar system. Considering the temporal dependence of intensity, the degree of anisotropy, and the direction in space from which ...
