Space Weather, Volume 24, Issue 4, April 2026.Abstract Equatorial plasma bubbles (EPBs) are plasma density depletion structures that produce magnetic field perturbations through the diamagnetic effect and therefore need to be identified and excluded in high‐precision geomagnetic field modeling. Traditional EPB detection methods typically rely on in situ electron density or total electron content ...

Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]
, 2014 The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with ...

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.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 ...

Modeling the geomagnetic field over Croatia
Geofizika, 2011 During the last years investigation of the geomagnetic field in Croatia has started and an effort to establish the geomagnetic observatory has been made. Based on the total field measured over the northern eastern part of Croatia, the suitable position for installing the geomagnetic observatory is proposed.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.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 ...

Geomagnetic ground survey in Slovakia for the 2007.5 epoch
Contributions to Geophysics and Geodesy, 2009 New geomagnetic ground survey was carried out in years 2006–2008. The survey was accomplished under fair geomagnetic-activity conditions during the minimum phase of a solar activity cycle No. 23. The measurements of the geomagnetic field

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract We analyze the response of mean winds and semidiurnal tides (SDTs) in the mesosphere and lower thermosphere (MLT; ∼70–110 km altitude) to the May 2024 geomagnetic super storm, based on meteor radar (MR) observations from King Sejong Station (KSS; geographic: 62.22°S, 58.78°W; geomagnetic: 53.27°S, 10.88°E) in the Antarctic Peninsula.
