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?

The NRL OSO-4 Bragg crystal spectrometer instrument [PDF]

open access: yes
Two Bragg crystal spectrometers were placed on the OSO-4 satellite to study solar flare plasmas by their spectral emissions. The solar flare plasma parameters were measured with these spectrometers, which together covered a total wavelength range of 0.6 ...

Uncovering the heterogeneity of a solar flare mechanism with mixture models

open access: yesFrontiers in Astronomy and Space Sciences
The physics of solar flares occurring on the Sun is highly complex and far from fully understood. However, observations show that solar eruptions are associated with the intense kilogauss fields of active regions, where free energies are stored with ...

The 1859 space weather event revisited: limits of extreme activity

open access: yesJournal of Space Weather and Space Climate, 2013
The solar flare on 1 September 1859 and its associated geomagnetic storm remain the standard for an extreme solar-terrestrial event. The most recent estimates of the flare soft X-ray (SXR) peak intensity and Dst magnetic storm index for this event are ...
