Multi‐Species Energy‐Banded Ions in the Ionosphere During the 21 January 2005 Magnetic Storm: Low‐Altitude Edge of the Warm Plasma Cloak

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract During the 21–22 January 2005 magnetic storm, the FAST satellite observed warm (< few keV) ions in discrete energy bands on the dayside at ∼3,000 km altitude for more than 6.5 hr. We suggest that the ionospheric energy‐banded ions represent the low‐altitude edge of the warm plasma cloak observed simultaneously by magnetospheric satellites ...

Comparative Analysis Of Interplanetary Magnetic Field And Moving Charged Particles [PDF]

, 2017
The discussion reviews the wave-particle duality of clouds of ions, protons and electron blown out from Sun and enter Earthrsquos magnetic field. They behave as particles when they are at rest or moving with uniform motion-velocity from the source or co ...

Deep Learning‐Based Prediction of High‐Speed Solar Wind Streams: Spatio‐Temporal Dependencies in Coronal Hole Dynamics

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract High‐speed solar wind streams (HSS), originating from coronal holes (CH), are key drivers of space weather disturbances and heliospheric dynamics. However, forecasting HSS remains challenging due to the evolving morphology of CH. In this study, we present a deep learning‐based framework that models the spatiotemporal relationship between CH ...

Development and Validation of the GEANT4 Model of the Electron Proton Helium Instrument on Board the SOHO Spacecraft Utilizing the Accelerator Measurements at the Hahn‐Meitner Institute Berlin

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Context. The Electron Proton Helium INstrument (EPHIN) aboard SOlar and Heliospheric Observatory is a particle telescope that measures energetic protons and helium above 4 MeV/nuc and electrons above 150 keV. While a calibration of EPHIN has been performed before launch, it has only partially been assessed reducing the accuracy of the detector

Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms

International Journal of Geophysics, 2011
An important issue in low-latitude ionospheric space weather is how magnetic storms affect the generation of equatorial plasma bubbles. In this study, we present the measurements of the ion density and velocity in the evening equatorial ionosphere by the

Can an interplanetary magnetic field reach the surface of Venus? [PDF]

Annales Geophysicae, 2018
We address the question of whether there is a possibility of an interplanetary magnetic field reaching Venus' surface by magnetic diffusion across the ionosphere.

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

Longitudinal Variability of Pre‐Midnight Equatorial Plasma Bubbles Under Disturbed Geomagnetic Conditions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Equatorial plasma bubbles (EPBs) pose significant challenges to trans‐ionospheric radio communication and navigation systems. Because of their disruptive effects, evaluating and predicting them is key for the development of space systems. The influence of geomagnetic activity on EPBs remains unclear, partly due to limited low‐latitude neutral ...

Role of Large‐Scale Traveling Ionospheric Disturbances in the Positive Storm Phase Observed by the Millstone Hill Radar and GNSS TEC Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract A moderate geomagnetic storm was driven by high‐speed solar wind stream on 14 March 2016. We show that large‐scale traveling ionospheric disturbances (LSTIDs) played a significant role in producing the ionospheric storm positive phase at mid‐latitudes in the North American sector.
