One of the grand challenges in heliophysics is the characterisation of coronal mass ejection (CME) magnetic structure and evolution from eruption at the Sun through heliospheric propagation. At present, the main difficulties are related to the lack of direct measurements of the coronal magnetic fields and the lack of 3D in-situ measurements of the CME body in interplanetary space. Nevertheless, the evolution of a CME magnetic structure can be followed using a combination of multi-point remote…

Effect of an interplanetary coronal mass ejection on Saturn's radio emission
The Saturn Kilometric Radiation (SKR) was observed for the first time during the flyby of Saturn by the Voyager spacecraft in 1980. These radio emissions, in the range of a few kHz to 1 MHz, are


The Interaction of Successive Coronal Mass Ejections: A Review
We present a review of the different aspects associated with the interaction of successive coronal mass ejections (CMEs) in the corona and inner heliosphere, focusing on the initiation of series of
Linking two consecutive nonmerging magnetic clouds with their solar sources
On 15 May 2005, a huge interplanetary coronal mass ejection (ICME) was observed near Earth. It triggered one of the most intense geomagnetic storms of solar cycle 23 (Dstpeak = −263 nT). This
Modelling a multi-spacecraft coronal mass ejection encounter with EUHFORIA
Coronal mass ejections (CMEs) are a manifestation of the Sun's eruptive nature. They can have a great impact on Earth, but also on human activity in space and on the ground. Therefore, modelling
Deflection of coronal mass ejection in the interplanetary medium
A solar coronal mass ejection (CME) is a large-scale eruption of plasma and magnetic fields from the Sun. It is believed to be the main source of strong interplanetary disturbances that may cause
Magnetic clouds seen at different locations in the heliosphere
We analyze two magnetic clouds (MCs) observed in different points of the heliosphere. The main aim of the present study is to provide a link between the different aspects of this phenomenon, starting
The life of a CME and the development of a MIR: From the Sun to 58 AU
[1] Large coronal mass ejections (CMEs) have major effects on the structure of the solar wind in the heliosphere. The plasma and magnetic field can be compressed ahead of CMEs to form merged
Remote and in situ observations of an unusual Earth‐directed coronal mass ejection from multiple viewpoints
[1] During June 16–21, 2010, an Earth-directed coronal mass ejection (CME) event was observed by instruments onboard STEREO, SOHO, MESSENGER and Wind. This event was the first direct detection of a
Coronal mass ejections are not coherent magnetohydrodynamic structures
The incoherence ofCMEs suggests interpretation of CME observations requires accurate reconstruction of the ambient solar wind with which they interact, and that simple assumptions about the shape of the CMEs are likely to be invalid when significant spatial/temporal gradients in ambientSolar wind conditions are present.
Rotation of Coronal Mass Ejections during Eruption
Understanding the connection between coronal mass ejections (CMEs) and their interplanetary counterparts (ICMEs) is one of the most important problems in solar-terrestrial physics. We calculate the
Sun to 1 AU propagation and evolution of a slow streamer-blowout coronal mass ejection
[1] We present a comprehensive analysis of the evolution of the classic, slow streamer-blowout CME of 1 June 2008 observed by the STEREO twin spacecraft to infer relevant properties of the
