Cosmic Ray Anisotropy Generated by the June 22nd 2015 Interplanetary Events

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract On 22 June 2015, the near Earth interplanetary space was perturbed by a series of high‐speed streamers and interplanetary coronal mass ejections associated with an active region and two low‐latitude coronal holes. The interaction of these disturbances gave rise to the complex solar wind structure observed at 1 au.

Strong Westward Current Pulse at Auroral Latitudes Extending to Dawn‐Side Low‐Latitudes Due To Enhanced Density Within Kelvin‐Helmholtz Wave Vortex in Solar Wind

Geophysical Research Letters
A series of coronal mass ejections (CMEs) from the Sun, interacted with one another and formed a complex interplanetary‐CME (ICME) that impinged Earth's magnetosphere on 10 May 2024 and caused the strongest geomagnetic storm of the past two decades.

Geomagnetic Polarity Timescale [PDF]

, 2001
Dating and time control are essential geoscience, because they allow us to rock sequences from different environments of deposition. Most importantly, accurate time control allows us to calculate rates of change, which is necessary for understanding underlying processes and mechanisms.

GIA‐Induced Mantle Circulation and Surface Horizontal Motions in North America: Effects of 3D Laterally Varying Elastic Thickness and Viscosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The horizontal surface motions of the Earth's crust induced by glacial isostatic adjustment (GIA) are highly sensitive to lateral variations in Earth properties. We construct 3D GIA models by incorporating both varying elastic lithospheric thickness and lateral viscosity variations in the asthenosphere in a global, compressible, self ...

Earthquakes and geomagnetic disturbances

Solnechno-Zemnaya Fizika, 2020
The article addresses the problem of the connection of earthquakes with geomagnetic phenomena. We have carried out an experimental study using a method based, firstly, on the separation of periods of geomagnetic activity into extremely quiet and disturbed, and, secondly, on the description of seismic activity with an index called the global daily ...

Magnetic field fluctuations coinciding with substorm events

Earth, Planets and Space
Using observations from the Van Allen Probes spacecraft, this study reports multifrequency banded magnetic field fluctuations during substorm-associated magnetic field dipolarization at L < 6.6.

Satellite Traces: Ionogram Signatures of Bottom‐Side Upwelling Structures ‐ A Simulation Study

Geophysical Research Letters
Satellite Traces (STs) are the important ionogram signatures for the presence of upwellings in the bottom‐side ionosphere, which provide the necessary seed perturbation for the development of equatorial plasma bubbles (EPBs).
