What Is the Lowest Latitude of Discrete Aurorae During Superstorms?

Space Weather
From a survey of published accounts of visual sightings of aurorae, a compilation is presented of the lowest identified geomagnetic latitude at which discrete aurorae were seen at local zenith during magnetic storms having intensities with maximum −Dst ...

The State of Solar Wind Heavy Ions in Interplanetary Coronal Mass Ejection–Driven Geomagnetic Storms

The Astrophysical Journal
During geomagnetic storms, which are the primary periods for heavy ions from the solar wind to enter Earth’s magnetospheric space, the charge state of solar wind heavy ions during these storms has significant implications for studying the distribution ...

The Characteristics and Possible Mechanisms of the Strongest Ionospheric Irregularities in March 2024

Atmosphere
A geomagnetic storm occurred on 3 March 2024, with the minimum SYM-H reaching −127 nT. Although this geomagnetic storm was not very strong, the ionospheric irregularities on this day resulted in a strong ionospheric scintillation.

Solar sources of geomagnetic storms

Eos, Transactions American Geophysical Union, 1992
Because geomagnetic storms can have important effects on communications and electrical power distribution, an ability to predict these storms has considerable value. We have recently come to understand that coronal mass ejections (CMEs) cause most large geomagnetic storms during the most active part of the solar cycle [Gosling et al., 1991].

Geomagnetic Storm Research Based on Recent Geomagnetic Explosion

International Journal of Applied Science
Geomagnetic storms, caused by disturbances in Earth’s mag- netosphere, have garnered significant attention due to their po-tential impact on technology and infrastructure. This article examines the origins and characteristics of geomagnetic storms, often triggered by solar activity like coronal mass ejections.
