Comparison of deep space and near-earth observations of plasma turbulence at solar wind discontinuities [PDF]
Simultaneous observations of plasma waves from the electric field instruments on Pioneer 9 and OGO 5 are used to illustrate the difference between near-earth and deep space conditions.

AATR an ionospheric activity indicator specifically based on GNSS measurements [PDF]
, 2018 This work reviews an ionospheric activity indicator useful for identifying disturbed periods affecting the performance of Global Navigation Satellite System (GNSS). This index is based in the Along Arc TEC Rate (AATR) and can be easily computed from dual-

Cosmic ray diffusion: Report of the Workshop in Cosmic Ray Diffusion Theory [PDF]
A workshop in cosmic ray diffusion theory was held at Goddard Space Flight Center on May 16-17, 1974. Topics discussed and summarized are: (1) cosmic ray measurements as related to diffusion theory; (2) quasi-linear theory, nonlinear theory, and computer

Mariner 10 magnetic field observations of the Venus wake [PDF]
Magnetic field measurements made over a 21-hour interval during the Mariner 10 encounter with Venus were used to study the down-stream region of the solar wind-Venus interaction over a distance of approximately 100 R sub v.

Journal of Atmospheric and Solar-Terrestrial Physics, 2011 Abstract We describe (i) perturbations of the magnetopause/magnetosphere elicited by an interplanetary discontinuity and (ii) the production of Kelvin–Helmholtz waves on the magnetopause. These are two large topics, so for reasons of space we combine both features in a single data example, supporting the observations by theory.

Coronal Alfven waves and the solar wind [PDF]
The observed properties of coronal Alfven waves in the solar wind at 1 AU are briefly reviewed, with some theoretical discussion of their probable effects on the dynamics of the expanding solar corona. It is concluded that coronal Alfven waves can have a

Fractal structure of the interplanetary magnetic field [PDF]
Under some conditions, time series of the interplanetary magnetic field strength and components have the properties of fractal curves. Magnetic field measurements made near 8.5 AU by Voyager 2 from June 5 to August 24, 1981 were self-similar over time ...

Fine-scale characteristics of interplanetary sector [PDF]
The structure of the interplanetary sector boundaries observed by Helios 1 within sector transition regions was studied. Such regions consist of intermediate (nonspiral) average field orientations in some cases, as well as a number of large angle ...

Consequences of using nonlinear particle trajectories to compute spatial diffusion coefficients [PDF]
The propagation of charged particles through interstellar and interplanetary space has often been described as a random process in which the particles are scattered by ambient electromagnetic turbulence.
