Dawn‐Side Anomaly in Sudden Geomagnetic Field Responses to Solar Wind Pressure Discontinuities During the 10 May and 10 October 2024 Geomagnetic Storms

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Interactions of solar wind dynamic pressure (SWDP) discontinuities with Earth's magnetosphere cause geomagnetic Sudden Commencements (SCs). Typically, positive/negative SCs occur at low latitudes due to enhancements/reductions in SWDP.

Are Nonthermal Velocities in Active Region Coronal Loops Anisotropic?

The Astrophysical Journal, 2023
We have measured line widths in active region coronal loops in order to determine whether the nonthermal broadening is anisotropic with respect to the magnetic field direction. These nonthermal velocities are caused by unresolved fluid motions.

Reflection of fast magnetosonic waves near magnetic reconnection region

, 2018
Magnetic reconnection in the solar corona is thought to be unstable to the formation of multiple interacting plasmoids, and previous studies have shown that plasmoid dynamics can trigger MHD waves of different modes propagating outward from the ...

Effects of the May 2024 Solar Storm on the Earth's Radiation Belts Observed by CALET on the International Space Station

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In May 2024, extraordinary solar activity triggered a powerful solar storm, impacting Earth and producing the extreme geomagnetic storm of 10‐11 May, the most intense since 2003. This had significant effects on the magnetosphere, leading to the creation of a new long‐lasting component of relativistic electrons and to flux changes in the South ...

75th Anniversary of ‘Existence of Electromagnetic-Hydrodynamic Waves’ [PDF]

, 2018
We have recently passed the 75th anniversary of one of the most important results in solar and space physics: Hannes Alfv\'en's discovery of Alfv\'en waves and the Alfv\'en speed. To celebrate the anniversary, this article recounts some major episodes in

Responses of a Coronal Hole to a Fast Flare-driven Coronal Wave

The Astrophysical Journal Letters
Coronal waves, significant solar phenomena, act as diagnostic tools for scientists studying solar atmosphere properties. Here, we present a novel observation detailing how a coronal wave event, associated with an X5.0 class flare, influenced the ...

Energy spectra of 3He-rich solar energetic particles associated with coronal waves

, 2016
In addition to their anomalous abundances, 3He-rich solar energetic particles (SEPs) show puzzling energy spectral shapes varying from rounded forms to power laws where the later are characteristics of shock acceleration. Solar sources of these particles

Analyzing Geomagnetic Data From the Dusheti Observatory During the Intense Magnetic Storms of 2024

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Geomagnetic storms, intense disturbances in the Earth's magnetosphere, pose risks to both technology and human activity in space. In this study, we analyzed geomagnetic field measurements from the Dusheti Observatory in Georgia during the intense geomagnetic storms of March 3, March 24, and 11 May 2024.
