Anisotropic Heating and Cooling within Interplanetary Coronal Mass Ejection Sheath Plasma

The Astrophysical Journal
This study presents the first comprehensive investigation of the relationship between heating and cooling, temperature anisotropy, turbulence level, and collisional age within interplanetary coronal mass ejection (ICME) sheaths, which are highly ...

Field‐Aligned Currents During High‐Intensity Long‐Duration Continuous Auroral Electrojet Activity Events: A Statistical Study

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Enhanced solar wind‐magnetosphere energy coupling during geomagnetic disturbances leads to strong geomagnetic field‐aligned currents (FACs). While variations of FACs during geomagnetic storms and substorms have been well explored, there is no systematic study of FACs during high‐intensity long‐duration continuous auroral electrojet activities (

Modeling of Magnetic Local Time Asymmetry in Storm‐Time Low‐Latitude Geomagnetic Field Disturbances Due To Partial Ring Current

Space Weather, Volume 23, Issue 11, November 2025.
Abstract The intensity of storm‐time disturbance in the ground magnetic field varies significantly at different longitudes due to the magnetic local time (MLT) dependent contributions from different magnetospheric and ionospheric currents. Local geomagnetic field disturbances at low‐to‐mid latitudes often deviate considerably from the global depression

Impact of the Gannon Superstorm on the Equatorial Ionization Anomaly Dynamics During Its Recovery Phase on 11 May 2024

Space Weather, Volume 23, Issue 11, November 2025.
Abstract During the recovery phase of the Gannon Superstorm on 11 May 2024, the thermosphere‐ionosphere system experienced dramatic changes marked by an unusual redistribution of plasma density. The peak electron density (Nmax) from Global‐scale Observations of the Limb and Disk (GOLD), ground‐based Vertical Total Electron Content (VTEC), and topside ...

Monitoring the Solar Wind Before It Reaches L1

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Space weather predictions of the solar wind impacting Earth are usually first based on remote‐sensing observations of the solar disc and corona, and eventually validated and/or refined with in situ measurements taken at the Sun–Earth Lagrange L1 point, where real‐time monitoring probes are located.

Solar Flare Activity, 1937–2024: Introducing the New Hemispheric Solar Flare Index (hSFI) in the Context of 2024's Major Solar Storm Events

Space Weather, Volume 23, Issue 11, November 2025.
Abstract A new daily composite of the solar flare index (SFI) and the hemispherically‐resolved versions (hSFI) are presented for 1937 to 2024. The data set confirms that the northern hemisphere (NH) dominated solar flare activity during Solar Cycles 17 to 21, but that the southern hemisphere has dominated from Solar Cycle 22 to present.

Earth's Alfvén Wings Driven by the April 2023 Coronal Mass Ejection

Geophysical Research Letters
We report a rare regime of Earth's magnetosphere interaction with sub‐Alfvénic solar wind in which the windsock‐like magnetosphere transforms into one with Alfvén wings.
