Probabilistic Geomagnetic Storm Forecasting via Deep Learning

Journal of Geophysical Research: Space Physics, 2020
Geomagnetic storms, which are governed by the plasma magnetohydrodynamics of the solar‐interplanetary‐magnetosphere system, entail a formidable challenge for physical forward modeling.

Response of the low- to mid-latitude ionosphere to the geomagnetic storm of September 2017

, 2020
. We study the impact of the geomagnetic storm of 7–9 September 2017 on the low- to mid-latitude ionosphere. The prominent feature of this solar event is the sequential occurrence of two SYM-H minima with values of −146 and −115  nT on 8 September at 01 ...

First Synoptic Observations of Geomagnetic Storm Effects on the Global‐Scale OI 135.6‐nm Dayglow in the Thermosphere by the GOLD Mission

Geophysical Research Letters, 2020
The Global‐scale Observations of the Limb and Disk (GOLD) mission provides, for the first time, a synoptic view of the thermospheric response to a moderate geomagnetic storm at a 30‐min cadence.

The effect of continuous geomagnetic storms on enhancements of ultrarelativistic electrons in the Earth’s outer radiation belt

Frontiers in Astronomy and Space Sciences
Ultrarelativistic electrons (Ek > 3 MeV) are the most energetic electrons in the Earth’s outer radiation belt, which can cause serious damage to equipments on satellites. The evolutions of ultrarelativistic electrons during geomagnetic storm have been

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 ...

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.

Ionospheric Response to the Extreme 2024 Mother's Day Geomagnetic Storm Over the Latin American Sector

Space Weather
Geomagnetic storms affect Earth in various severe ways, including damaging satellites, disrupting power grids, and inducing prompt penetration electric fields (PPEF) through Joule heating in the auroral region. They also cause disturbance dynamo electric

Solar Flare and Geomagnetic Storm Effects on the Thermosphere and Ionosphere During 6–11 September 2017

Journal of Geophysical Research: Space Physics, 2019
The period of 6–11 September 2017 was an active period in which multiple solar flares and a major geomagnetic storm occurred. The two largest flares, an X9.3 and an X8.2, were a disk flare and a limb flare, respectively.
