Geomagnetic storms driven by ICME- and CIR-dominated solar wind. [PDF]

, 2006
The interaction of the solar wind and the Earth's magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejections (ICMEs) compared to solar wind dominated by corotating

Statistical Analysis of Magnetic Field Fluctuations in Coronal Mass Ejection-Driven Sheath Regions [PDF]

, 2021
We report a statistical analysis of magnetic field fluctuations in 79 coronal mass ejection(CME-) driven sheath regions that were observed in the near-Earth solar wind. Wind highresolution magnetic field data were used to investigate 2 h regions adjacent

The response of the magnetosphere to the passage of a coronal mass ejection on March 20-21 1990 [PDF]

, 1997
International audienceThe geomagnetic response to the passage of a coronal mass ejection (CME) is studied. The passage of the CME resulted in a storm sudden commencement (SSC) at 2243 UT on March 20 1990 with disturbed magnetic activity during the ...

A Simulation of a Coronal Mass Ejection Propagation and Shock Evolution in the Lower Solar Corona

The Astrophysical Journal, 2008
We present a detailed simulation of the evolution of a moderately slow coronal mass ejection (CME; 800 km s−1 at 5 R☉, where R☉ is solar radii) in the lower solar corona (2-5 R☉). The configuration of the Sun's magnetic field is based on the MDI data for the solar surface during Carrington rotation 1922.

Tracing solar wind plasma entry into the magnetosphere using ion-to-electron temperature ratio [PDF]

, 2009
When the solar wind Mach number is low, typically such as in magnetic clouds, the physics of the bow shock leads to a downstream ion-to-electron temperature ratio that can be notably lower than usual.

MAGNETIC FIELD STRENGTH IN THE UPPER SOLAR CORONA USING WHITE-LIGHT SHOCK STRUCTURES SURROUNDING CORONAL MASS EJECTIONS [PDF]

The Astrophysical Journal, 2012
To measure the magnetic field strength in the solar corona, we examined 10 fast (> 1000 km/s) limb CMEs which show clear shock structures in SOHO/LASCO images. By applying piston-shock relationship to the observed CME's standoff distance and electron density compression ratio, we estimated the Mach number, Alfven speed, and magnetic field strength ...

The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005 [PDF]

, 2007
International audienceThe arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ~09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF).

Proton Acceleration In Coronal Shocks [PDF]

, 2013
<p>Solar energetic particles (SEP) are produced in powerful eruptions originating on the Sun. In past decades, there has been considerable debate and even confusion as to what the primary source of SEPs is - flares low in the corona, or coronal ...
