Why torus-unstable solar filaments experience failed eruption? [PDF]

, 2019
To investigate the factors that control the success and/or failure of solar eruptions, we study the magnetic field and 3-Dimensional (3D) configuration of 16 filament eruptions during 2010 July - 2013 February.

The Dominant Role of the Electron Isotropy Boundary in Controlling Earth's Outer Radiation Belt Electron Lifetimes

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Field‐line curvature scattering (FLCS) is believed to be the primary mechanism forming electron isotropy boundaries (IB) and can rapidly scatter relativistic electrons from the outer radiation belt. However, its direct and quantitative impact on controlling outer belt electron lifetimes has never been directly assessed.

Real Heights of SuperDARN F Region Echoes Inferred From Electron Density Measurements by the Rankin Inlet and RISR‐C Radars

Radio Science, Volume 61, Issue 2, February 2026.
Abstract This study is one of the first attempts to estimate statistically the real height of SuperDARN F region echoes in the polar cap. To achieve this, measurements of the electron density in the scattering volume of the Rankin Inlet SuperDARN radar are compared with the electron density profiles measured by the incoherent scatter radar RISR‐C ...

Geospace Environment Modeling Program

Eos, Transactions American Geophysical Union, 1992
The geospace environment encompasses the highest and largest of the four physical geospheres—lithosphere, hydrosphere, atmosphere, and magnetosphere. Despite its size, its far‐reaching structures interconnect and move together in a choreography of organized dynamics, whose complexity is reflected in the intricate movements of the northern lights.

Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.

Radar detection of a localized 1.4 Hz pulsation in auroral plasma, simultaneous with pulsating optical emissions, during a substorm [PDF]

Annales Geophysicae, 2010
Many pulsating phenomena are associated with the auroral substorm. It has been considered that some of these phenomena involve kilometer-scale Alfvén waves coupling the magnetosphere and ionosphere.

Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question. This is due to their global presence, which cannot be fully quantified by spatially limited observations, and the need for ...

GENERAL SCIENTIFIC PRECONDITIONS AND PROSPECTS OF PREDICTION OF GEOSPACE PROCESSES FOR THE BENEFIT OF THE SUSTAINABLE DEVELOPMENT OF TERRITORIES

InterCarto. InterGIS, 2016
This work substantiates the need to ontologically couple methods of prediction of geospace processes and fundamental bases of the modern epistemological picture of the world. The method of a structural mask of power geographical fields is offered. On its
