Frontiers in Astronomy and Space Sciences, 2019 Diagnosing the solar atmospheric plasma is one of the major challenges in solar physics. Magnetohydrodynamic (MHD) waves, by means of applying the powerful concept of solar magneto-seismology (SMS), provide a tool to obtain diagnostic insight into the ...

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 ...

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.

On the topology of global coronal magnetic fields [PDF]
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Space Weather, Volume 23, Issue 10, October 2025.Abstract As the 25th solar cycle enters a highly active phase, the resulting ionospheric irregularities induce disturbances in signals of Global Navigation Satellite System (GNSS), significantly disrupting its global stable positioning, navigation, and timing services.

Development and application of a global magnetic field evolution model for the solar corona [PDF]
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Measuring the Coronal Magnetic Field with 2D Coronal Seismology: A Forward-modeling Validation
The Astrophysical Journal Supplement SeriesIn recent years, a two-dimensional (2D) coronal seismology technique applied to spectral-imaging data from the Coronal Multi-channel Polarimeter (CoMP) and Upgraded Coronal Multi-channel Polarimeter (UCoMP) has enabled routine measurement of the global ...

Space Weather, Volume 23, Issue 10, October 2025.Abstract Based on the total electron content (TEC) observation in the Asian‐Australian and American sectors, this paper investigates the characteristics and hemispheric asymmetry of large‐scale traveling ionospheric disturbances (LSTIDs) during the 10 May 2024 superstorm. We found that the amplitudes and meridional phase velocities of LSTIDs in the two

Damping and Dispersion of Acoustic Waves in the Solar Corona
The Astrophysical JournalWe study one of the most common phenomena in the solar corona—compression waves observed in the extreme ultraviolet range. They are observed throughout various coronal structures, coronal loops and holes.
