The Stellar CME-flare relation: What do historic observations reveal? [PDF]

Astrophysical Journal, 2019
Solar CMEs and flares have a statistically well defined relation, with more energetic X-ray flares corresponding to faster and more massive CMEs. How this relation extends to more magnetically active stars is a subject of open research.

Quantifying errors in 3D CME parameters derived from synthetic data using white-light reconstruction techniques [PDF]

Advances in Space Research, 2022
Current e ff orts in space weather forecasting of CMEs have been focused on predicting their arrival time and magnetic structure. To make these predictions, methods have been developed to derive the true CME speed, size, position, and mass, among others ...

In situ multi-spacecraft and remote imaging observations of the first CME detected by Solar Orbiter and BepiColombo [PDF]

Astronomy & Astrophysics, 2020
On April 19th 2020 a CME was detected by Solar Orbiter at a heliocentric distance of 0.8 AU and was also observed in-situ on April 20th by both Wind and BepiColombo.

Solar Flare–CME Coupling throughout Two Acceleration Phases of a Fast CME [PDF]

Astrophysical Journal, 2020
Solar flares and coronal mass ejections (CMEs) are closely coupled through magnetic reconnection. CMEs are usually accelerated impulsively within the low solar corona, synchronized with the impulsive flare energy release.

CME–CME Interactions as Sources of CME Geoeffectiveness: The Formation of the Complex Ejecta and Intense Geomagnetic Storm in 2017 Early September [PDF]

Astrophysical Journal Supplement Series, 2019
Coronal mass ejections (CMEs) are the primary sources of intense disturbances at Earth, where their geoeffectiveness is largely determined by their dynamic pressure and internal magnetic field, which can be significantly altered during interactions with ...

Forecasting the Arrival Time of Coronal Mass Ejections: Analysis of the CCMC CME Scoreboard [PDF]

Space Weather, 2018
Accurate forecasting of the properties of coronal mass ejections (CMEs) as they approach Earth is now recognized as an important strategic objective for both NOAA and NASA.

CME–HSS Interaction and Characteristics Tracked from Sun to Earth [PDF]

Solar Physics, 2019
In a thorough study, we investigate the origin of a remarkable plasma and magnetic field configuration observed in situ on June 22, 2011, near L1, which appears to be a magnetic ejecta (ME) and a shock signature engulfed by a solar wind high-speed stream

Drifting of the line-tied footpoints of CME flux-ropes [PDF]

Astronomy & Astrophysics, 2018
Context. Bridging the gap between heliospheric and solar observations of eruptions requires the mapping of interplanetary coronal mass ejection (CME) footpoints down to the Sun’s surface. But this not straightforward.

WISPR Imaging of a Pristine CME [PDF]

Astrophysical Journal Supplement Series, 2019
The Wide-field Imager for Solar Probe (WISPR) on board the Parker Solar Probe (PSP) observed a coronal mass ejection (CME) on 2018 November 1, the first day of the initial PSP encounter.
