MMS Observations of the Energetic Particles Within Kelvin‐Helmholtz Waves at the Boundary of the 10 May 2024 Coronal Mass Ejection (CME)

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 10 May 2024, Earth was hit by a CME that drove the largest geomagnetic storm in 20 years. Multi‐spacecraft observations previously showed that the ∼100 nT north‐south IMF bz ${b}_{z}$ variation was driven by Kelvin‐Helmholtz waves with wavelength ∼250 RE ${R}_{E}$ and reconnection jets in the ±z $\pm z$‐direction (Nykyri, 2024a, https://doi.

Shock waves propagation in the turbulent interplanetary plasma [PDF]

Advances in Space Research, 1996
AbstractEffect of turbulence on interplanetary shock waves propagation is considered. It is shown that background turbulence results in the additional shock wave deceleration which may be comparable with the deceleration due to plasma sweeping. The turbulent deceleration is connected with the energy losses due to the strong turbulence amplification ...

Soft Proton Environment Modeling for SMILE Using XGBoost and Solar Cycle–Informed Synthetic Data Sets

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Soft proton contamination presents a persistent threat to the performance of space‐based X‐ray observatories such as ESA's upcoming Solar‐wind Magnetosphere Ionosphere Link Explorer (SMILE). This study develops a machine‐learning framework for modeling soft proton fluxes in the 92.2–159.7 keV range, tailored to SMILE's elliptical, highly ...

A case study of large-amplitude ULF waves in the Martian foreshock

Earth and Planetary Physics, 2020
Foreshock ultralow frequency (ULF) waves constitute a significant physical phenomenon in the plasma environment of terrestrial planets. The occurrence of these waves, associated with backstreaming particles reflected and accelerated at the bow shock ...

A Model for Recommending Historical Similar Events in Forecasting CME Geoeffectiveness

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Coronal mass ejections (CMEs) are among the key solar eruptive activities, triggering space weather disturbances. Thus, forecasting their geoeffectiveness has become a research focus. This study constructs a model to recommend similar events for forecasting the geoeffectiveness of CMEs.

Large, Long‐Lasting Mid‐Latitude Geomagnetically Induced Currents During a Moderate Geomagnetic Storm

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Geomagnetically Induced Currents (GICs) are a key space weather hazard to ground‐based infrastructure, and can cause mis‐operation or even equipment failure. The solar wind interacts with the Earth's geomagnetic field, causing the magnetic field at ground level to vary with time.

The response of the magnetosphere to the passage of a coronal mass ejection on March 20-21 1990 [PDF]

, 1997
International audienceThe geomagnetic response to the passage of a coronal mass ejection (CME) is studied. The passage of the CME resulted in a storm sudden commencement (SSC) at 2243 UT on March 20 1990 with disturbed magnetic activity during the ...

Frequency‐Dependent Acoustic Reflection Coefficients of Flat Ground Assessed Using the Sonic Boom From the OSIRIS‐Rex Sample Return Capsule Recorded on Free Flying Balloons

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Low frequency sound can travel great distances in planetary atmospheres. When these waves reflect off the air/ground interface, energy may be absorbed or transferred to mechanical waves in the subsurface. This study describes the direct and reflected acoustic wave generated by the re‐entry of the OSIRIS‐REx Sample Return Capsule captured on a ...

Assessing electron heat flux dropouts as signatures of magnetic field line disconnection from the Sun

, 2005
Suprathermal electrons focused along magnetic field lines, called the strahl, carry heat flux away from the Sun. Various factors can cause heat flux dropouts (HFDs), including times when the strahl almost vanishes.

A solar storm observed from the Sun to Venus using the STEREO, Venus Express, and MESSENGER spacecraft [PDF]

, 2009
The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007 ...
