Geomagnetic storm related to intense solar radio burst type II and III due to M3.9 class flare and coronal mass ejections [PDF]

open access: yes, 2018
The strong energetic particles ejected during sun’s activity will propagate towards earth and contribute to solar radio bursts. These solar radio bursts can be detected using CALLISTO system.

Assessing the Performance of GPS Precise Point Positioning Under Different Geomagnetic Storm Conditions during Solar Cycle 24

open access: yesItalian National Conference on Sensors, 2018
The geomagnetic storm, which is an abnormal space weather phenomenon, can sometimes severely affect GPS signal propagation, thereby impacting the performance of GPS precise point positioning (PPP).

The 2015 Summer Solstice Storm: one of the major geomagnetic storms of solar cycle 24 observed at ground level [PDF]

open access: yes, 2018
We report on the 22-23 June 2015 geomagnetic storm. There has been a shortage of intense geomagnetic storms during the current solar cycle 24 in relation to the previous cycle. This situation changed after mid-June 2015 when one of the biggest solar active regions (AR 2371) of current solar cycle 24, close to the central meridian produced several ...

The Extreme Space Weather Event in February/March 1941 [PDF]

open access: yesThe Astrophysical Journal, 2020, 2020
Given the infrequency of extreme geomagnetic storms, it is significant to note the concentration of three extreme geomagnetic storms in 1941, whose intensities ranked fourth, twelfth, and fifth within the aa index between 1868-2010. Among them, the geomagnetic storm on 1 March 1941 was so intense that three of the four Dst station magnetograms went off

Quantifying extreme behaviour in geomagnetic activity [PDF]

open access: yes, 2011
Understanding the extremes in geomagnetic activity is an important component in understanding just how severe conditions can become in the terrestrial space environment. Extreme activity also has consequences for technological systems.

Modeling the Depletion and Recovery of the Outer Radiation Belt During a Geomagnetic Storm: Combined MHD and Test Particle Simulations

open access: yesJournal of Geophysical Research: Space Physics, 2018
During geomagnetic storms the intensities of the outer radiation belt electron population can exhibit dramatic variability. Deep depletions in intensity during the main phase are followed by increases during the recovery phase, often to levels that ...

A Study of the Morphology of Magnetic Storms: Moderate Magnetic Storms [PDF]

open access: yes, 1957
Some average characteristics are determined for 136 moderate magnetic storms with sudden commencements that occurred during the interval 1902-1945.

A Carrington-like geomagnetic storm observed in the 21st century [PDF]

open access: yes, 2015
In September 1859 the Colaba observatory measured the most extreme geomagnetic disturbance ever recorded at low latitudes related to solar activity: the Carrington storm.

TID Observations and Source Analysis During the 2017 Memorial Day Weekend Geomagnetic Storm Over North America

open access: yesJournal of Geophysical Research: Space Physics, 2018
We investigate ionospheric perturbations associated with traveling ionospheric disturbance (TID) during the geomagnetic storm on Memorial Day weekend (28 May) 2017.
