Space Weather, Volume 24, Issue 3, March 2026.Abstract Complex space weather, such as typhoons and solar activity, can cause heavy rainfall and ionospheric disturbances, affecting the quality of Global Navigation Satellite System (GNSS) signals. Among GNSS positioning techniques, Precise Point Positioning Real‐time Kinematic (PPP‐RTK) uses atmospheric corrections and bias products to achieve fast ...

An overview of coronal seismology
, 2005 The idea of exploiting observed oscillations as a diagnostic tool for determining the physical conditions of the coronal plasma was first suggested several decades ago (Roberts et al. 1984 Astrophys. J. 279, 857).

Space Weather, Volume 24, Issue 2, February 2026.Abstract A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming, we develop a “4π $4{\uppi }$” full‐heliosphere event forecasting framework and evaluate its statistical classification ability against this specific challenge.

Propagation and damping of MHD waves in the solar atmosphere [PDF]
, 2015 Quasi-periodic disturbances have been observed in the outer solar atmosphere for many years. Although first interpreted as upflows (Schrijver et al.

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops
The Astrophysical JournalDecayless 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 (

Space Weather, Volume 24, Issue 2, February 2026.Abstract On 10 May 2024, a severe G5 geomagnetic storm—the most intense of solar cycle 25—significantly disturbed the global ionosphere. This study presents a comprehensive analysis using multi‐instrument observations, including ground‐based measurements from BDS‐GEO total electron content (TEC), digital ionosondes, and magnetometers; model outputs ...

Effect of Solar Flares on Decayless Kink Oscillations in Nearby Coronal Loops
The Astrophysical JournalWe present a statistical study of 130 solar flares (B to X class) that lack soft X-ray quasiperiodic pulsations and show no kink oscillations of nearby coronal loops visible in Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly (AIA) 171 Å ...

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 ...

Nonlinear Wave Damping by Kelvin–Helmholtz Instability-induced Turbulence
The Astrophysical JournalMagnetohydrodynamic 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

The modeling of quasi-periodic oscillations propagation in the solar corona
Современная наука и инновацииIn 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.
