Midlatitude ionospheric F2-layer response to eruptive solar events-caused geomagnetic disturbances over Hungary during the maximum of the solar cycle 24: a case study [PDF]
Adv.Space.Res.61:1230-1243,2018, 2018 In our study we analyze and compare the response and behavior of the ionospheric F2 and of the sporadic E-layer during three strong (i.e., Dst <-100nT) individual geomagnetic storms from years 2012, 2013 and 2015, winter time period. The data was provided by the state-of the art digital ionosonde of the Sz\'echenyi Istv\'an Geophysical Observatory ...

Satellite Drag Analysis During the May 2024 Gannon Geomagnetic Storm [PDF]
Journal of Spacecraft and Rockets 2024 61:5, 1412-1416Between May 10-12, 2024, Earth saw its largest geomagnetic storm in over 20 years. Since the last major storm in 2003, the population of satellites in low Earth orbit has surged following the commercialization of space services and the ongoing establishment of proliferated LEO constellations.

Characterization of G -Semigroup by Intuitionistic N-Fuzzy Set (INFS) and its level set [PDF]
, 2017 Some characterizations of G -Semigroup by intuitionistic N-fuzzy sets have been given here. The concept of intuitionistic N-fuzzy set (INFS) and its level set has been applied to G -semigroup.

Observations of Low‐Latitude Red Aurora in Mexico During the 1859 Carrington Geomagnetic Storm
Space Weather, 2018 One of the most intense geomagnetic storm that has been documented in recent history occurred on 1 September 1859. This storm is known as the Carrington Event.

A Machine Learning and Computer Vision Approach to Geomagnetic Storm Forecasting [PDF]
arXiv, 2022 Geomagnetic storms, disturbances of Earth's magnetosphere caused by masses of charged particles being emitted from the Sun, are an uncontrollable threat to modern technology. Notably, they have the potential to damage satellites and cause instability in power grids on Earth, among other disasters.

The Influence of Internal Atmospheric Variability on the Ionosphere Response to a Geomagnetic Storm
, 2018 The Whole Atmosphere Community Climate Model eXtended is used to investigate the extent to which neglecting the realistic day‐to‐day lower atmospheric variability introduces uncertainty in the ionosphere response to an idealized geomagnetic storm.

Geoelectric Field Evaluation During the September 2017 Geomagnetic Storm: MA.I.GIC. Model
Space Weather, 2019 The space environment near Earth is constantly subjected to changes in the solar wind flow generated at the Sun. Examples of this variability are the occurrence of powerful solar disturbances, such as coronal mass ejections (CMEs).
