From the Sun to Earth: effects of the 25 August 2018 geomagnetic storm
. On 25 August 2018 the interplanetary counterpart of the 20 August 2018 coronal mass ejection (CME) hit Earth, giving rise to a strong G3 geomagnetic storm. We present a description of the whole sequence of events from the Sun to the ground as well as a

Statistical nature of geomagnetic storms [PDF]
On the basis of geomagnetic activity indices and solar wind parameters, a superposed epoch analysis has been conducted for more than 300 geomagnetic storms. The intensity of magnetic storms is found to depend on the duration of the main phase; larger storms have longer timescales.

Characteristics and Importance of “ICME-in-sheath” Phenomenon and Upper Limit for Geomagnetic Storm Activity [PDF]
As an important source for large geomagnetic storms, an “ICME-in-sheath” is a completely shocked interplanetary coronal mass ejection (ICME) stuck in the sheath between a shock and host ejecta.

Two Notable Geomagnetic Storms [PDF]
Disturbances of considerable intensity, comprising two distinct geomagnetic storms, occurred during the interval March 23–29, 1946. Displays of the Aurora Borealis have been reported; there was dislocation over long‐distance radio channels and, in the case of the second storm, with submarine‐cable telegraphy.

Characteristics of a Gradual Filament Eruption and Subsequent CME Propagation in Relation to a Strong Geomagnetic Storm [PDF]
An unexpected strong geomagnetic storm occurred on 2018 August 26, which was caused by a slow coronal mass ejection (CME) from a gradual eruption of a large quiet-region filament. We investigate the eruption and propagation characteristics of this CME in

In this paper, we presented the effect of moderate geomagnetic storms on the TEC variation at the Koudougou station (Geo Lat 12° 15′ N; Geo Long: -2° 20′ E) in Burkina Faso (Africa) during the descending phase of solar cycle 24.

Can Smartphones Detect Geomagnetic Storms? [PDF]
AbstractSeveral smartphone models on the Android and iOS platforms have been investigated for their ability to detect geomagnetic storms. Although this capability could have scientific application, there is a growing commercial interest in using smartphones for precision location applications not involving the GPS system.

In solar cycle 24, the strongest geomagnetic storm took place on March 17, 2015, when the geomagnetic activity index was as high as -223 nT. To verify the impact that the storm had on the Global Navigation Satellite System (GNSS)’s positioning accuracy ...
