Two Notable Geomagnetic Storms [PDF]
Nature, 1946 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.

Risk assessment of power system oscillation instability based on geomagnetic storm events in the 24th solar cycle [PDF]
IET Generation, Transmission & Distribution, 2022 When studying the harm of geomagnetic storms to the power system, the focus is often placed on the influence of transformers reactive power loss (GIC‐Q) caused by geomagnetic induced current (GIC) on voltage fluctuation.

DAYTIME ELECTRON DENSITY AT IONOSPHERIC F1-LAYER HEIGHTS DURING GEOMAGNETIC STORMS (IRKUTSK)
Solar-Terrestrial Physics, 2022 We have examined variations in electron density Ne at ionospheric F1-layer heights during geomagnetic storms at the Irkutsk ionospheric station (52° N, 104° E). We have selected geomagnetic storms of varying intensity as well as quiet days for each event

Ionospheric redistribution during geomagnetic storms. [PDF]
J Geophys Res Space Phys, 2013 The abundance of plasma in the daytime ionosphere is often seen to grow greatly during geomagnetic storms. Recent reports suggest that the magnitude of the plasma density enhancement depends on the UT of storm onset. This possibility is investigated over a 7year period using global maps of ionospheric total electron content (TEC) produced at the Jet ...

A Statistical Study of the Correlation between Geomagnetic Storms and M ≥ 7.0 Global Earthquakes during 1957–2020 [PDF]
Entropy, 2020 In order to find out whether the geomagnetic storms and large-mega earthquakes are correlated or not, statistical studies based on Superposed Epoch Analysis (SEA), significance analysis, and Z test have been applied to the Dst index data and M ≥ 7.0 ...

A study of geomagnetic storms [PDF]
, 1975 Twenty-one geomagnetic storm events during 1966 and 1970 were studied by using simultaneous interplanetary magnetic field and plasma parameters. Explorer 33 and 35 field and plasma data were analyzed on large-scale (hourly) and small-scale (3 min ...

Statistical study and corresponding evolution of plasmaspheric plumes under different levels of geomagnetic storms [PDF]
Annales Geophysicae, 2022 Using observations of Van Allen Probes, we present a statistical study of plasmaspheric plumes in the inner magnetosphere. Plasmaspheric plumes tend to occur during the recovery phase of geomagnetic storms.
