Geomagnetic extreme statistics for Europe [PDF]

open access: yes, 2009
Rapidly changing geomagnetic field variations constitute a natural hazard, for example to grounded power grids and pipeline networks. To understand this hazard we have continuous magnetic measurements across the world for typically less than 100 years.

Enhancement of Terrestrial Diffuse X-ray Emission Associated With Coronal Mass Ejection and Geomagnetic Storm

open access: yes, 2011
We present an analysis of a Suzaku observation taken during the geomagnetic storm of 2005 August 23-24. We found time variation of diffuse soft X-ray emission when a coronal mass ejection hit Earth and caused a geomagnetic storm.

A Physics‐Informed Neural Network Approach to the Gannon Storm

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Extreme geomagnetic storms, such as the May 2024 Gannon event, pose significant risks to technological infrastructure, requiring robust forecasting models. Here, we apply Physics‐Informed Neural Networks (PINNs) to the Burton equation to model the storm's ring current dynamics by studying the temporal evolution of the SuperMAG SMR index during

Daytime Ionospheric Density Enhancement Driven by Poleward Neutral Wind Shear Associated With Gravity Waves During the November 2025 Geomagnetic Storm

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The threefold daytime electron density increases, along with strong poleward meridional winds exceeding 200 m/s were captured by Sanya Incoherent Scatter Radar (SYISR) during the geomagnetic storm of 12 November 2025. The great ionospheric enhancements were extending to mid‐latitudes over 40° observed by total electron content (TEC) from ...

A Safety Evaluation Method for a Power System Influenced by a Geomagnetic Storm

open access: yesIEEE Access, 2020
Geomagnetic storm disasters have a significant impact on the safe and stable operation of power systems. Serious geomagnetic storm disasters can lead to cascading accidents in power systems, up to and including voltage collapse accidents.

Solar Transients disturbing the Terrestrial Magnetic Environment at Higher Latitudes

open access: yes, 2013
Geomagnetic field variations during five major Solar Energetic Particle (SEP) events of solar cycle 23 have been investigated in the present study. The SEP events of 01 oct 2001, 04 Nov 2001, 21 Apr 2002 and 14 May 2005 have been selected to study the ...

Bioinspired Sensory Transduction for Magnetic Profile Recognition and Encryption

open access: yesAdvanced Materials, Volume 38, Issue 24, 27 April 2026.
Magnetic sensing in nature relies on dynamic transduction pathways, yet synthetic counterparts remain limited. We introduce a bioinspired system that couples electromagnetic induction in moldable magnetic soft composites with machine learning to encode and decode static (shape, rheology, magnetization) and dynamic (magnetization decay) magnetic ...

First Record of Dark‐sided Flycatcher (Muscicapa sibirica) for Temperate North America: Intercontinental Vagrancy and Migratory Misorientation

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We document the extraordinary occurrence of a Dark‐sided Flycatcher (Muscicapa sibirica)—a migratory passerine from East Asia—in California, USA. We discuss the little‐known phenomenon of intercontinental vagrancy in migratory landbirds and examine this case study in detail, providing analysis of the age, molt status, subspecies, and likely origins of ...
