A Statistical Study of Photospheric Magnetic Field Changes During 75 Solar Flares
, 2018 Abrupt and permanent changes of photospheric magnetic fields have been observed during solar flares. The changes seem to be linked to the reconfiguration of magnetic fields, but their origin is still unclear.

Mars Thermospheric Polar Warming at Aphelion: Dynamical Processes Studied Using M‐GITM
Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Aphelion Thermospheric Polar Warming (TPW), first identified in 2024 by Mars Atmosphere and Volatile EvolutioN (MAVEN) observations, is a dynamical heating phenomenon in the Martian atmosphere that exists in the winter hemisphere near the aphelion solstice.

Human‐Interpretable SEP Event Prediction Using White‐Box Explainable AI
Space Weather, Volume 24, Issue 4, April 2026.Abstract Solar energetic particle (SEP) events pose radiation risks to astronauts and space systems, making their prediction essential. Although various prediction models have been developed, most machine learning (ML)‐based models lack interpretability; that is, it is difficult to explain the reasons behind individual predictions.

Reconstructing Historical Solar Indices for Predicting Past Space Weather Events
Space Weather, Volume 24, Issue 4, April 2026.Abstract Modeling and forecasting the near‐Earth space environment, specifically the thermosphere, is particularly important because it affects the motion of low‐Earth orbit objects through atmospheric drag. Solar indices such as F10.7, S10.7, M10.7, and Y10.7 are commonly used as inputs to ionospheric and thermospheric density models.

Solar flares and energetic particles [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 Solar flares are now observed at all wavelengths from γ -rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract The state of Mars' induced magnetosphere is highly dependent on upstream solar wind conditions. Changes in dynamic pressure alter the locations of magnetospheric boundaries such as the bow shock and induced magnetosphere boundary, while the orientation of the interplanetary magnetic field (IMF) impacts the formation of the bow shock.
