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 ...

PLASMA AND MAGNETIC FIELD CHARACTERISTICS OF SOLAR CORONAL MASS EJECTIONS IN RELATION TO GEOMAGNETIC STORM INTENSITY AND VARIABILITY [PDF]

, 2015
The largest geomagnetic storms of solar cycle 24 so far occurred on 2015 March 17 and June 22 with D[subscript st] minima of -223 and -195 nT, respectively. Both of the geomagnetic storms show a multi-step development.

Geomagnetic Storm Related to Disturbance Storm Time Indices

European Journal of Environment and Earth Sciences, 2021
The magnitude of the Disturbance Storm Time (Dst) index varied in relation to the extremely small negative integer that indicated a large geomagnetic storm. The large sharpened variants of negative Dst indices could describe the detailed features of a geomagnetic storm.

Geoeffectiveness of Coronal Mass Ejections in the SOHO era

, 2014
The main objective of the study is to determine the probability distributions of the geomagnetic Dst index as a function of the coronal mass ejection (CME) and solar flare parameters for the purpose of establishing a probabilistic forecast tool for the ...

Spremembe v gostoti energije magnetnega polja Zemlje na observatoriju PIA, Slovenija, med geomagnetno nevihto G5 11. maja 2024 (= Changes in the energy density of the Earth's magnetic field at the PIA, Slovenia, observatory during the G5 Geomagnetic Storm on May 11, 2024)

Geodetski Vestnik
Geomagnetic storms are the largest disturbance in the Earth's magnetic field. On May 11, 2024, a geomagnetic storm occurred at the peak of the 25th solar cycle, reaching the highest level (G5) on the planetary scale.

A study of geomagnetic storms [PDF]

Geophysical Journal International, 1978
The interplanetary energy flux is estimated on the basis of the Poynting flux and its variations with the rate of energy dissipation in terms of: (1) the ring-current particle injection, (2) Joule dissipation in the ionosphere, and (3) auroral particle injection for 15 major geomagnetic storms.
