Simultaneous interplanetary scintillation and Heliospheric Imager observations of a coronal mass ejection [PDF]

, 2008
We describe simultaneous Interplanetary Scintillation (IPS) and STEREO Heliospheric Imager (HI) observations of a coronal mass ejection (CME) on 16 May 2007. Strong CME signatures were present throughout the IPS observation.

Compression of the Earth's magnetotail by interplanetary shocks directly drives transient magnetic flux closure [PDF]

, 2006
We use a novel method to evaluate the global opening and closure of magnetic flux in the terrestrial system, and to analyse two interplanetary shock passages that occurred during magnetically quiet periods. We find that, even under these quiet conditions,

IMF dependence of the open-closed field line boundary in Saturn's ionosphere, and its relation to the UV auroral oval observed by the Hubble Space Telescope [PDF]

, 2007
We study the dependence of Saturn's magnetospheric magnetic field structure on the interplanetary magnetic field (IMF), together with the corresponding variations of the open-closed field line boundary in the ionosphere.

A solar storm observed from the Sun to Venus using the STEREO, Venus Express, and MESSENGER spacecraft [PDF]

, 2009
The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007 ...

Observations of ionospheric flows and particle precipitation following a Sudden Commencement [PDF]

Annales Geophysicae, 2000
On May 4, 1998, at 0227 UT an interplanetary shock crossed the WIND spacecraft, and half an hour later a Sudden Commencement occurred. Coinciding with the Sudden Commencement a rapid intensification of the flux of particle precipitation into the ...

Developments in the use of EISCAT for interplanetary scintillation [PDF]

, 2008
The antennas of EISCAT have been used for interplanetary scintillation (IPS) studies of the solar wind for many years. The main science found from these studies is obtained through the cross-correlation of signals from antennas having the longest ...

Quantifying the Agyrotropy of Proton and Electron Heating in Turbulent Plasmas

The Astrophysical Journal, 2023
An important aspect of energy dissipation in weakly collisional plasmas is that of energy partitioning between different species (e.g., protons and electrons) and between different energy channels.

Cluster observations of the midaltitude cusp under strong northward interplanetary magnetic field [PDF]

, 2008
We report on a multispacecraft cusp observation lasting more than 100 min. We determine the cusp boundary motion and reveal the effect on the cusp size of the interplanetary magnetic field (IMF) changing from southward to northward.

Planar Magnetic Structures Downstream of Coronal Mass Ejection–driven Shocks in the Inner Heliosphere

The Astrophysical Journal, 2023
Planar magnetic structures (PMSs), characterized by interplanetary magnetic field vectors remaining parallel to a specific plane, are commonly observed in the solar wind, especially in the sheath region of interplanetary coronal mass ejections (ICMEs ...
