Role of solar flare index in long term modulation of cosmic ray intensity [PDF]

open access: yes
Recently, the importance of the occurrence of solar flares in the long-term modulation of cosmic ray intensity has been re-emphasized. For this purpose, the data of solar flares have been used from various publications, such as Solar Geophysical Data ...

The Solar Flares Demonstrate the Solar Interior Layers: The Inner and Backside Solar Flares

open access: yes, 2022
Although the Sun is a huge gaseous body, the solar inner layers are not visible, with the opacity of the convection zone. Moreover, the surface events are related to or extended from the solar interior layers according to the previous study such as [12]. Is it possible that the location of the surface events are related to the inner layers?

Integration of solar flare and coronal mass ejection event dataHarvard Dataverse

open access: yesData in Brief
Solar flares and coronal mass ejections are solar transient events that can impact our technological infrastructure in near-Earth and Earth environments. While related, not all flares generate CMEs and there are a limited number of resources that connect

Multiclass Classification of Solar Flares in Imbalanced Data Using Ensemble Learning and Sampling Methods

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
Solar flares are intense bursts of radiation across the electromagnetic spectrum on the surface of the Sun. They are categorized into four classes: B, C, M, and X, depending on their intensity, with X-class flares being the strongest.

Solar Flares Triggered by a Filament Peeling Process Revealed by High-resolution GST Hα Observations

open access: yesThe Astrophysical Journal Letters
The dynamic structures of solar filaments prior to solar flares provide important physical clues about the onset of solar eruptions. Observations of those structures under subarcsecond resolution with high cadence are rare.
