Global Effect of Long‐Lasting 07–12 October 2024 Geomagnetic Storms During the Transition From a Strong (G3) to a Severe (G4) on the Geomagnetic Field and Ionospheric Parameters Distribution

open access: yesSpace Weather, Volume 24, Issue 7, July 2026.
Abstract This study investigates the co‐evolution of geomagnetic field disturbances with ionospheric parameters and their characteristic latitudinal signatures by conducting a location and time‐dependent analysis of the 07–12 October 2024 events, to fill crucial gaps in understanding the coupled response of the magnetosphere‐ionosphere system. This has

Development and application of a global magnetic field evolution model for the solar corona [PDF]

open access: yes, 2009
Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

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 ...

High-resolution Observation of Solar Prominence Plumes Induced by Enhanced Spicular Activity

open access: yesThe Astrophysical Journal Letters
Solar prominences are the most prominent large-scale structures observed above the solar limb in emission in chromospheric lines but in absorption in coronal lines. At the bottom of prominences often appears a bubble, with plumes occasionally rising from

Characterizing Patterns of Resurfacing on Venus With Volcanoes and Coronae

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract One of the major research questions for Venus is the manner in which it resurfaces itself, with a near‐random distribution of a relatively few craters providing the only age constraints for the planet's surface. We use volcanoes and their temporal and spatial relationships to coronae to characterize patterns of coronal resurfacing for ...

Recurrently Propagating Intensity Disturbances along Polar Plumes Observed in White Light and Extreme Ultraviolet

open access: yesThe Astrophysical Journal
We study properties of intensity disturbances along polar coronal rays that are associated with plumes below. For this, we draw azimuth–time images of extreme ultraviolet (EUV) emission of 171 Å band observed by the SDO/AIA and white light (WL) observed ...

Evolution of Magnetospheric Boundary Layers Under the 10 May 2024 ICME Impact

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract On 10 May 2024, an interplanetary coronal mass ejection‐driven shock impacted the dayside magnetopause, compressing it to ∼5 RE. A northward interplanetary magnetic field suppressed dayside reconnection and allowed a clear investigation of the magnetosphere response.

Simulations of Structured Upflows from Plumes and Their Connection to the Solar Wind

open access: yesThe Astrophysical Journal Letters
Small-scale transient jetlet activity and associated upflows from coronal hole plumes are potential sources of the solar wind. To elucidate the magnetic origins and driving mechanisms of such upflows, we perform three-dimensional (3D) radiative ...

Unraveling Super Equatorial Plasma Bubbles (EPBs) Evolution During the 23 April 2023 Storm: Multi‐Instrument Observations and GITM‐SAMI3 Simulation

open access: yesSpace Weather, Volume 24, Issue 4, April 2026.
Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.

Bright Dots and Coronal Plume Formation in Sunspot Penumbra

open access: yesThe Astrophysical Journal
Coronal plumes are narrow, collimated structures that are primarily viewed above the solar poles and in coronal holes in the extreme ultraviolet, but also in sunspots.
