Correlation between the solar wind speed and the passage of poleward-moving auroral forms into the polar cap

Frontiers in Astronomy and Space Sciences
In 1961, Dungey suggested that magnetic reconnection occurs due to the solar-terrestrial interaction. The interplanetary magnetic field (IMF) is thought to merge with Earth’s geomagnetic field (GMF).

High Latitude Thermosphere and Ionosphere Density Response to the May 2024 Geomagnetic Storm Observed by the LLITED CubeSat Mission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The May 2024 G5 geomagnetic storm produced significant disturbances in the ionosphere and thermosphere, particularly at high latitudes. Using high‐resolution in situ ion and neutral density measurements from the NASA Low‐Latitude Ionosphere/Thermosphere Enhancements in Density (LLITED) CubeSat at 430 km altitude, this study documents notable ...

Differences between CME-driven storms and CIR-driven storms [PDF]

, 2006
Twenty one differences between CME-driven geomagnetic storms and CIR-driven geomagnetic storms are tabulated. (CME-driven includes driving by CME sheaths, by magnetic clouds, and by ejecta; CIR-driven includes driving by the associated recurring high ...

Statistical Study on Pulsating Auroras and High‐Latitude Propagation of Chorus Waves Based on Conjugate Observations of Ground‐Based Imagers and Arase Satellite

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Pulsating aurora (PsA) is one of the common diffuse auroras typically generated by ∼10 keV electron precipitation. Precipitating electrons are scattered via wave‐particle interactions with whistler‐mode chorus waves in the magnetosphere. Previous studies have observationally demonstrated that, during PsAs, highly energetic electrons with ...

Quasi‐Periodic X‐Ray Variations at BARREL: Role of Electron Precipitation and Solar Wind Driving

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) mission was designed to study the loss of radiation belt electrons to the upper atmosphere. Previous analysis of data from balloon pairs showed that electron precipitation events manifest coherent quasi‐periodic variations (with periodicity on the order of 10–60 min ...

Capturing Secondary Kinetic Instabilities in Three‐Dimensional Dayside Reconnection Using an Improved Gradient‐Based Closure

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower‐hybrid drift and secondary drift‐kink instabilities in particular have been shown by kinetic simulations to modify the reconnection and introduce significant turbulence and ...

The Partition of Energy Flux Transport at Bursty Bulk Flows

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Bursty bulk flows (BBFs) are fast flows of plasma in the tail and are responsible for much of the energy flux transport earthward from the tail into the inner magnetosphere despite being relatively short‐lived. BBFs are often accompanied by injections in which particles that have been accelerated to 10–100s of keV are transported earthward. We

A Statistical Study of Warm Plasma Cloak Particles Using Van Allen Probe Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The Warm Plasma Cloak (WPC) consists of ions in the inner magnetosphere with energies between 10 eV and 1 keV and showing a bidirectional pitch angle distribution of particles. These particles play an important role in wave–particle interactions and in controlling the dayside reconnection rate at the magnetopause.

Evolution and characteristics of global pc5 ULF waves during a high solar wind speed interval [PDF]

, 2005
We present an interval of extremely long-lasting narrow-band Pc5 pulsations during the recovery phase of a large geomagnetic storm. These pulsations occurred continuously for many hours and were observed throughout the magnetosphere and in the dusk ...

Extension, Improvements and Perspectives of the Cluster GRMB Data Set

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract The purpose of the Geospace Region and Magnetospheric Boundary identification (GRMB) data set is to provide information on the regions crossed by each of the 4 Cluster spacecraft during the entire mission. The data set includes 15 labels, 11 for regions and transition regions (TR): plasmasphere, plasmapause TR, plasmasheet, plasmasheet TR ...
