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 ...

Recent geomagnetic storms observed by Macau Science Satellite-1
Geomagnetic storms are rapid disturbances of the Earth’s magnetosphere. They are related to many geophysical phenomena and have large influences on human activities.

Wavelet analysis of the ionospheric response at mid-latitudes during the April 200 storm using magnetograms and vTEC from GPS [PDF]
In this work we pursue the idea of computing a parameter that allows us to estimate the local ionospheric response to a geospheric event that triggers an ionospheric storm. For that, wavelet technique has been chosen because of its ability to analyze non-

Why Coronal Mass Ejections Arrive Differently: Solar Cycle Modulation Through Solar Wind Structure
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

A Study of the Morphology of Magnetic Storms Great Magnetic Storms [PDF]
Average characteristics are determined for 74 great magnetic storms with sudden commencements that occurred in 1902-1945. The storm field is resolved for different epochs of storm time into tv;o parts: (i) Dst, which is independent of local time, that

Abstract As we move into the declining phase of solar cycle 25, the sunspot number is going down but space weather impacts are not disappearing. Solar energetic particle events, large x‐ray flares, and geomagnetic storms are still happening and the declining phase will bring a different balance of hazards.

Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...

Abstract Ultra‐low‐frequency (ULF) waves cause local Thermosphere‐Ionosphere (T‐I) perturbations, but their impacts on the global T‐I system including the generation of Traveling Atmospheric Disturbances (TADs) have never been evaluated. The mechanisms responsible for the TAD generation and propagation, whether through dynamic or thermal process, are ...
