Space Weather, Volume 24, Issue 4, April 2026.Abstract The total electron content (TEC) in the ionosphere is strongly affected by solar activity and geomagnetic disturbances in mid‐ and low‐latitude regions, making it a major source of error in GNSS navigation and communication systems. To improve the prediction accuracy of ionospheric TEC, this study proposes a deep learning model—Beluga Whale ...

Why Coronal Mass Ejections Arrive Differently: Solar Cycle Modulation Through Solar Wind Structure
Space Weather, Volume 24, Issue 4, April 2026.Abstract Coronal Mass Ejections (CMEs) are large structures of magnetized plasma ejected from the Sun's atmosphere into the heliosphere. The interaction of CMEs with the ambient solar wind during propagation affects arrival time and speed at Earth. Since the solar wind structure changes with the solar cycle, variability in the transit times and arrival

Does the current minimum validate (or invalidate) cycle prediction methods? [PDF]
, 2010 This deep, extended solar minimum and the slow start to Cycle 24 strongly suggest that Cycle 24 will be a small cycle. A wide array of solar cycle prediction techniques have been applied to predicting the amplitude of Cycle 24 with widely different ...

Space Weather, Volume 24, Issue 4, April 2026.Abstract The South Atlantic Anomaly (SAA) in Earth's radiation belt is a critical region that poses significant threats to the safety of Space Stations. This region harbors a high concentration of energetic particles that can penetrate Space Stations, thereby affecting onboard components and posing risks to astronauts.

Geomagnetic Main-Field Modelling with POGS Satellite Data
Journal of geomagnetism and geoelectricity, 1997 Models of the geomagnetic main field of degree and order 13 are constructed for epoch 1992.5. These are based on combinations of (quiet-time, low activity) Polar Orbiting Geomagnetic Survey (POGS) total intensity data, and various near-surface, largely vector, measurements.
