Modeling the Excitation, Propagation, and Damping of Quasiperiodic Fast Magnetosonic Waves in Realistic Coronal Active Region Magnetic Field Structures

The Astrophysical Journal
Quasiperiodic fast propagating (QFP) magnetosonic waves have been discovered in the solar corona in the extreme ultraviolet (EUV) since the launch of the Solar Dynamics Observatory (SDO) spacecraft more than a decade ago.

Impacts of Space Weather‐Induced Satellite Navigation Errors on UAV Path Planning and Energy Consumption

Space Weather, Volume 24, Issue 1, January 2026.
Abstract Space weather disturbances can degrade satellite navigation accuracy, posing operational challenges for Unmanned Aerial Vehicle (UAV) missions that require precise path planning. This study investigates the impact of space weather‐induced horizontal navigation errors on UAV flight distance and energy consumption through a simulation‐based ...

Magneto-seismology: effect of inhomogeneous magnetic field on transversal coronal loop oscillations [PDF]

, 2008
The extreme-ultraviolet (EUV) imagers onboard the planned Solar Dynamics Observatory (SDO) and Solar Orbiter (SO) will offer us the best chance yet of using observations of post-flare loop oscillations to probe the fine structure of the corona.

FHD: An Extended Disturbance Storm‐Time Index Based on Fitted Functions of Horizontal Geomagnetic Field Variation

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The significant decrease in the global horizontal geomagnetic field is a key indicator of global magnetic storms and serves as the fundamental basis for deriving traditional disturbance storm‐time indices in space weather monitoring. The disturbance intensity varies across regions and with magnetic local time, highlighting the need for more ...

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops

The Astrophysical Journal
Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

The modeling of quasi-periodic oscillations propagation in the solar corona

Современная наука и инновации
In the general problem of oscillations observed in the solar corona, a particularly intriguing position is occupied by quasi-periodic oscillations, which are often observed in coronal holes.

Longitudinal oscillations in density stratified and expanding solar waveguides

, 2012
Waves and oscillations can provide vital information about the internal structure of waveguides they propagate in. Here, we analytically investigate the effects of density and magnetic stratification on linear longitudinal magnetohydrodynamic (MHD) waves.

Coronal global EIT waves as tools for multiple diagnostics [PDF]

, 2007
Observations in EUV lines of the solar corona revealed large scale propagating waves generated by eruptive events able to travel across the solar disk for large distances. In the low corona, CMEs are known to generate, e.g. EIT waves which can be used to

Monitoring the Solar Wind Before It Reaches L1

Space Weather, Volume 23, Issue 11, November 2025.
Abstract Space weather predictions of the solar wind impacting Earth are usually first based on remote‐sensing observations of the solar disc and corona, and eventually validated and/or refined with in situ measurements taken at the Sun–Earth Lagrange L1 point, where real‐time monitoring probes are located.

Nonlinear Wave Damping by Kelvin–Helmholtz Instability-induced Turbulence

The Astrophysical Journal
Magnetohydrodynamic kink waves naturally form as a consequence of perturbations to a structured medium, for example, transverse oscillations of coronal loops. Linear theory has provided many insights into the evolution of linear oscillations, and results
