Space weather and coronal mass ejections

open access: yes, 2013
Space weather has attracted a lot of attention in recent times. Severe space weather can disrupt spacecraft, and on Earth can be the cause of power outages and power station failure.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

open access: yesRadio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Can we detect coronal mass ejections through asymmetries of Sun-as-a-star extreme-ultraviolet spectral line profiles?

open access: yes, 2022
Coronal mass ejections (CMEs) are the largest-scale eruptive phenomena in the solar system. Associated with enormous plasma ejections and energy release, CMEs have an important impact on the solar-terrestrial environment.

Identifying and Predicting Coronal Mass Ejection Occurrence: Observational Checklists for Space Weather Forecasters

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Coronal Mass Ejections: Observations

open access: yes, 2012
Solar eruptive phenomena embrace a variety of eruptions, including flares, solar energetic particles, and radio bursts. Since the vast majority of these are associated with the eruption, development, and evolution of coronal mass ejections (CMEs), we ...

Space Weather Effects From Moderate to Severe Geomagnetic Storms in October 2024 Over the Latin American Sector

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract This study presents a detailed case study of the ionospheric impacts of moderate (G2) and severe (G4) geomagnetic storms over the Latin American sector, with particular emphasis on the formation and suppression of equatorial plasma bubbles (EPBs).

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Advancing Heliophysics and Space Weather Modeling Through Open Science

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

Solar Wind–Magnetosphere–Ionosphere Coupling Under Extreme External Driving: Characteristics of Dayside Ground Magnetic Disturbances

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The objective of the present study is to investigate solar wind‐magnetosphere‐ionosphere coupling (SWMIC) under intense external driving in terms of dayside ground magnetic disturbances. Dayside magnetic reconnection drives a region‐1 sense current system, the SWMIC current system.

Statistical Properties of Small‐Scale Magnetic Flux Ropes in the Near‐Earth Solar Wind

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present a statistical analysis of small‐scale magnetic flux ropes (SMFRs) observed in the near‐Earth solar wind using data from the Magnetospheric Multiscale (MMS) and Wind spacecraft, identified through an automated Grad–Shafranov reconstruction technique.
