Serendipitous observation of a coronal mass ejection during the total solar eclipse of 14 December 2020 [PDF]
We report observations of the total solar eclipse of 14 December 2020, during which a coronal mass ejection can be see n propagating. A comprehensive set of photographs covering a high dynamic range of exposure allow to characterize its dimensions. The displacement of the front can be seen occurring during the few minutes of totality.

On the Construction of Phenomenological Coronal Mass Ejection Models
We consider recently developed 3DCORE coronal mass ejection (CME) model. We find that the magnetic field of 3DCORE violates both Maxwellian equations: the one for absence of magnetic monopoles and the other one for Faraday induction (“frozen‐in ...

Earth-affecting solar transients: a review of progresses in solar cycle 24
This review article summarizes the advancement in the studies of Earth-affecting solar transients in the last decade that encompasses most of solar cycle 24. It is a part of the effort of the International Study of Earth-affecting Solar Transients (ISEST)

Simulation study on the propagation process of coronal mass ejection
Coronal mass ejection (CME) is a kind of space weather phenomenon caused by the intense activity of the sun. Important issues of concern to the space weather community include understanding the propagation and evolution of a particular CME in the corona ...

Proton beam velocity distributions in an interplanetary coronal mass ejection [PDF]
The plasma and magnetic-field instruments on the Helios 2 spacecraft, which was on 3 April 1979 located at 0.68 AU, detected an interplanetary coronal mass ejection (ICME) that revealed itself by the typical signature of magnetic field rotation.

Planar magnetic structures in coronal mass ejection-driven sheath regions [PDF]
Planar magnetic structures (PMSs) are periods in the solar wind during which interplanetary magnetic field vectors are nearly parallel to a single plane.

The Inhomogeneity of Composition Along the Magnetic Cloud Axis
Coronal mass ejections (CMEs) are one of the most energetic explosions in the solar system. It is generally accepted that CMEs result from eruptions of magnetic flux ropes, which are dubbed as magnetic clouds (MCs) in interplanetary space.

Influence of coronal holes on CME deflections: numerical study [PDF]
The understanding of the causes that produce the deflection of coronal mass ejections (CMEs) is essential for the space weather forecast. In this article, we study the effects on CMEs trajectories produced by the different properties of a coronal hole close to the ejection area.

Deciphering the Slow-rise Precursor of a Major Coronal Mass Ejection
Coronal mass ejections are explosive plasma phenomena prevalently occurring on the Sun and probably on other magnetically active stars. However, how their pre-eruptive configuration evolves toward the main explosion remains elusive.
