Semiannual variation of geomagnetic activity
TL;DR: In this article, it was proposed that the semiannual variation in geomagnetic activity is caused by a semiannually variation in the effective southward component of the interplanetary field.

Signature in the interplanetary medium for substorms.
TL;DR: In this article, a detailed signature for individual substorms is sought in the interplanetary medium, and the magnitude of the integral or summation of Bz south over time for the hour preceding the AE hourly average appears to be linearly related to the hourly average of AE.

Inward motion of the magnetopause before a substorm
TL;DR: Magnetopause inward motion before substorm, showing association with interplanetary field vertical component reversal as mentioned in this paper, was found to be associated with inter-planetary magnetic fields.
Journal ArticleDOI
The interplanetary magnetic field - Solar origin and terrestrial effects.
TL;DR: In this paper, it is suggested that there may be a rather continual relation between this solar structure and terrestrial responses, of which the recurring M-Region geomagnetic storms are just the most prominent example.
Journal ArticleDOI
OGO-A magnetic field observations
TL;DR: Magnetic field observations by OGO-A, with profiles of bow shock and magnetopause encounters as mentioned in this paper, were used to study the magnetic field of the bow shock. But the results were limited.

Interplanetary Magnetic Field and the Auroral Zones
TL;DR: In this article, it was found that a model with a southward interplanetary magnetic field leads to a natural explanation of the SD currents and speculative aspects of the problem as they appear at this time are discussed.

The solar wind velocity and its correlation with cosmic-ray variations and with solar and geomagnetic activity
TL;DR: Mariner 2 obtained data on the interplanetary plasma during the period August 29, 1962, through January 3, 1963, and compared with data on cosmic-ray diurnal variations and with indices of solar and geomagnetic activity for this period as discussed by the authors.
Journal ArticleDOI
Initial results of the imp 1 magnetic field experiment
TL;DR: In this paper, the initial results of the detailed measurements of the interplanetary magnetic field and the interaction of the solar wind with the geomagnetic field are presented, with extreme values as low as 1 and as high as 10 γ.
