Evolution of Anemone AR NOAA 10798 and the Related Geo-Effective Flares and CMEs

, 2008
We present a detailed examination of the features of the Active Region (AR) NOAA 10798. This AR generated coronal mass ejections (CMEs) that caused a large geomagnetic storm on 24 August 2005 with the minimum Dst index of -216 nT.

Investigation of the geomagnetic storms’ impact on low-latitude ionosphere: case studies of October 2003 and March 2015 events

Proceedings of the Nigerian Society of Physical Sciences
Geomagnetic storms can significantly impact the Earth's upper atmosphere known as the ionosphere used for communication and navigation, particularly at low latitudes.

TEC enhancement due to energetic electrons above Taiwan and the West Pacific

, 2013
The energetic electrons of the inner radiation belt during a geomagnetic disturbance can penetrate in the forbidden range of drift shells located at the heights of the topside equatorial ionosphere (

What is a geomagnetic storm?

Journal of Geophysical Research: Space Physics, 1994
After a brief review of magnetospheric and interplanetary phenomena for intervals with enhanced solar wind‐magnetosphere interaction, an attempt is made to define a geomagnetic storm as an interval of time when a sufficiently intense and long‐lasting interplanetary convection electric field leads, through a substantial energization in the magnetosphere‐

ASSESSMENT OF THE SEVERE GEOMAGNETIC STORM ON MAY 10-11, 2024 EFFECTS ON THE GEOMAGNETIC FIELD AND IONOSPHERE OVER THE INDONESIAN REGION

Rudarsko-geološko-naftni Zbornik
The severe geomagnetic storm on May 11, 2024, is the largest space weather phenomenon in the 25th solar cycle. This paper presents the impact of that severe geomagnetic storm (Dst = -412 nT) on the geomagnetic field and ionosphere over Indonesia ...

Explicit IMF $B_y$-effect maximizes at subauroral latitudes (Dedicated to the memory of Eigil Friis-Christensen)

, 2019
The most important parameter in the coupling between solar wind and geomagnetic activity is the $B_z$-component of the interplanetary magnetic field (IMF).

Satellites to study geomagnetic storms [PDF]

Eos, Transactions American Geophysical Union, 2007
NASA's Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission to study geomagnetic substorms over the next two years launched on 17 February from Cape Canaveral Air Force Station, Fla. Substorms are visible in the atmosphere as a sudden brightening of polar auroral ribbons as they split and reorganize, and are thought to ...

Occurrence of ionospheric scintillation during geomagnetic storms in Indonesia (2003–2024) using superposed epoch analysis

Earth and Planetary Physics
Ionospheric scintillation refers to rapid radio signal amplitude and phase fluctuations due to small-scale irregularities in the ionosphere. Occurring primarily at equatorial and low latitudes, scintillation is linked to equatorial plasma bubbles (EPBs),
