Analysis for the results of geomagnetic storms measured by Macau Science Satellite-1
Earth and Planetary PhysicsStrong flares and/or coronal mass ejections (CMEs) could bring us disastrous space weather, destroy crucial technology in space, and cause a large-scale blackout during some extreme cases.

The CME link to geomagnetic storms [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractThe coronal mass ejection (CME) link to geomagnetic storms stems from the southward component of the interplanetary magnetic field contained in the CME flux ropes and in the sheath between the flux rope and the CME-driven shock. A typical storm-causing CME is characterized by (i) high speed, (ii) large angular width (mostly halos and partial ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract On 23 November 2022, during exceptionally quiet geomagnetic conditions, a distinct ultra‐low frequency (ULF) wave in the Pc5 band (∼2.4 mHz) was observed in the duskside sub‐auroral region by two Canadian SuperDARN (Super Dual Auroral Radar Network) radars.

Strong geomagnetic disturbances and induced currents on Earth surface [PDF]
, 2008 Long-term variations in strong geomagnetic storms are analyzed and linked to electric fields induced on Earth. In fact, geomagnetic disturbances generate electric fields that drive currents in the Earth which may have significant effects on electrical ...

Ionospheric effetcs of an intense geomagnetic storm
Studia Geophysica et Geodaetica, 2007 An investigation of the response of the mid-high, mid and low latitude critical frequency foF2 to the geomagnetic storm of 15 July 2000 is made. Ground-based hourly foF2 values (proportional to square root of peak electron density of F2-layer) from four chains of ionospheric stations located in the geographic longitude ranges 10°W–35°E, 60°E–120°E, 130°

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract This study introduces a novel thermospheric disturbance index, JpT ${J}_{p}^{T}$, designed to describe density variations during geomagnetic storms. The index is constructed by applying the spectral whitening method to thermospheric density data derived from precise orbit determination of satellites from 2015 to 2019.

Solar cycle phase and occurrence of intense geomagnetic storms
Earth, Planets and SpaceSolar cycles have an asymmetrical shape with a fast rise and a slow decline, which varies from cycle to cycle. This makes it difficult to study the solar cycle phase dependence of the occurrence of intense solar-terrestrial events such as intense ...

Mid-latitude ionosphere during two great geomagnetic storms
Annals of Geophysics, 1996 The ionospheric disturbances observed at many European ionosonde stations in association with the severe geomagnetic storms occurring on 19-20 December 1980 and 11-12 April 1981 were investigated by using the available ionospheric and geomagnetic data ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract We analyze the May 2024 geomagnetic storm using a unique longitudinal chain of Antarctic stations, including the new remote Talos Dome measurement site. By combining its high‐resolution magnetic data with observed values from coastal (Terra Nova Bay and Scott Base) and the polar‐cap (Dome C) observatories, Southern Hemisphere auroral indices ...
