The Geomagnetic Storm on 10–12 May 2024 and Its Effect on the Swedish Power Grid

Space Weather, Volume 24, Issue 2, February 2026.
Abstract On 10–12 May 2024, at least five interplanetary coronal mass ejections (ICMEs) arrived at Earth and caused the strongest geomagnetic storm in over 20 years. During this geomagnetic storm, a disturbance occurred in a transformer in southern Sweden, causing a drop in power supply in the power line connecting Sweden and Poland.

Origin of Intense Plasma Depletions After Midnight Over the Korean Peninsula During the Geomagnetic Storm on 11 May 2024

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract A band of total electron content (TEC) depletions of about 5–15 TEC unit passed over the Korean Peninsula after midnight during the geomagnetic storm on 11 May 2024. This magnitude of TEC depletions has not been previously reported in the region.

Comparison of Ground‐Based Ionospheric Scintillation Observations With In Situ Electron Density Variations as Measured by the Swarm Satellites

Radio Science, 2019
Ionospheric scintillation is known to be associated with irregularities in electron density, which manifests as rapid fluctuations in the amplitude and phase of radio signals traversing the ionosphere. The scintillations caused by irregularity structures

Equatorial Ionospheric Scintillation Measurement in Advanced Land Observing Satellite Phased Array-Type L-Band Synthetic Aperture Radar Observations

Engineering
Amplitude stripes imposed by ionospheric scintillation have been frequently observed in many of the equatorial nighttime acquisitions of the Advanced Land Observing Satellite (ALOS) Phased Array-type L-band Synthetic Aperture Radar (PALSAR). This type of

Ionospheric Scintillation Activity Over Ilorin, Nigeria

Space Weather, 2018
AbstractScintillation of radio waves in the L‐band frequency is a regular occurrence at the equatorial and auroral regions at night most especially during high solar activity periods. Scintillation is caused by plasma density irregularities, and this could cause loss of lock of Global Navigation Satellite System (GNSS) signals leading to impairment of ...

Role of the external drivers in the occurrence of low-latitude ionospheric scintillation revealed by multi-scale analysis

URSI Asia-Pacific Radio Science Conference, 2019
In the low latitude ionosphere, the formation of Equatorial Plasma Bubbles presents a regular behavior under quiet conditions of the geospace. The ionospheric irregularities embedded in the plasma bubbles may lead to amplitude scintillation of Global ...

GNSS ionospheric scintillation studies in Singapore [PDF]

, 2019
Ionospheric scintillation has been a challenge for Global Navigation Satellites System (GNSS) application especially in equatorial region. Ionosphere in around equatorial region is known to have unique characteristic. The existence of horizontal geomagnetic field and eastward electric field in this region caused equatorial ionosphere anomaly (EIA ...
