Interplanetary magnetic field rotations followed from L1 to the ground : the response of the Earth's magnetosphere as seen by multi-spacecraft and ground-based observations [PDF]

, 2011
A study of the interaction of solar wind magnetic field rotations with the Earth's magnetosphere is performed. For this event there is, for the first time, a full coverage over the dayside magnetosphere with multiple (multi)spacecraft missions from dawn ...

Long-lived Magnetic Switchbacks Tracked across 0.32 au through BepiColombo–Solar Orbiter Radial Alignment

The Astrophysical Journal Letters
Magnetic switchbacks, often observed in the near-Sun solar wind, have received increased interest in recent years due to their potential role in mediating the heating and acceleration of the solar wind, but their origin remains debated.

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.

A Overview of Interplanetary Scintillation Method for Studying Solar Wind Physics

Journal of Astronomy and Space Sciences, 1988
Interplanetary scintillation is the fluctuation produced in the apparent brightness of a radio source, due to refractive effects in the turbulent solar wind flowing from the sun. If this medium is illuminated coherently, analysis of the spatial and temporal properties of the radiation reaching the earth allows the stochastic properties of the medium to

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.

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 ...

Dynamical age of solar wind turbulence in the outer heliosphere [PDF]

, 1998
In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.

Multiple Flux Rope Dynamics: MMS Observations and Reconstruction Results

The Astrophysical Journal
A series of six ion-scale magnetic flux ropes (FR1–6) and a thin current sheet, encountered by Magnetospheric Multiscale spacecraft in the magnetosheath side of the dayside magnetopause boundary layer, are studied for multiple flux rope dynamics in terms

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Seasonal influence on polar cap patches in the high-latitude nightside ionosphere [PDF]

, 2010
The influence of the season on the patch-to-background density ratio of polar cap patches in the nightside ionosphere was observed above northern Scandinavia around solar maximum (1999–2001).
