Forecasting Periods of Strong Southward Magnetic Field Following Interplanetary Shocks

, 2018
Long periods of strong southward magnetic fields are known to be the primary cause of intense geomagnetic storms. The majority of such events are caused by the passage over Earth of a magnetic ejecta.

Preliminary investigation of interplanetary shock structure: Quasi-parallel shocks

, 1974
Pioneer 9's magnetic field and plasma data were studied to develop arguments for or against the observation of oblique interplanetary shocks. Structural classifications are defined, and the justification for seeking these classifications in the solar ...

Multiple spacecraft observations of interplanetary shocks: Characteristics of the upstream ULF turbulence

, 1982
All interplanetary shocks observed by ISEE-3 and either ISEE-1 or ISEE-2 or both in 1978 and 1979 are examined for evidence of upstream waves. In order to characterize the properties of these shocks it is necessary to determine accurate shock normals. An

Radar detection of interplanetary shocks : scattering by anisotropic Langmuir turbulence

, 2010
Earth-directed interplanetary shocks associated with coronal mass ejections (CMEs) are known to have a severe impact on the magnetosphere, causing strong geomagnetic storms and substorms. Hence, early detection of such shocks is important.

Evolution of Electron Acceleration by Corotating Interaction Region Shocks at 1 au

The Astrophysical Journal Letters
We present the first observations of in situ electron acceleration at corotating interaction region (CIR) shocks near 1 au, utilizing measurements from Wind and Magnetospheric Multiscale (MMS) mission in the interplanetary medium. As the forward (reverse)

Proton Temperature Anisotropy across Interplanetary Shocks: A Statistical Analysis with WIND Observations

The Astrophysical Journal Letters
Interplanetary (IP) shocks efficiently modify the proton temperature anisotropy of the solar wind. Analyzing ∼800 IP shocks observed by the Wind spacecraft from 1997 to 2024, we present a statistical study of upstream and downstream proton temperature ...

The Speed of Interplanetary Shocks Through the Magnetosheath: A Toy Model

Before interacting with the magnetosphere, an interplanetary shock travels through the magnetosheath where its speed and shape are modified. Previous studies have reported widely different answers to the question of the speed of an interplanetary shock ...
