Decay of the coronal magnetic field can release sufficient energy to power a solar flare
Science, 2020 Magnetic energy release in a solar flare Solar flares are bright flashes and associated eruptions of plasma from the Sun that are thought to be powered by violent rearrangement of the magnetic fields near sunspots. Fleishman et al.

Observation of a reversal of rotation in a sunspot during a solar flare [PDF]
Nature Communications, 2016 Back reaction of coronal magnetic fields on the solar surface may help to understand the coronal reconfiguration during a solar flare. Here the authors report observation of reversal of the rotation of a sunspot during a X1.6 flare with data from HMI.

Unprecedented Fine Structure of a Solar Flare Revealed by the 1.6 m New Solar Telescope. [PDF]
Sci Rep, 2016 Solar flares signify the sudden release of magnetic energy and are sources of so called space weather. The fine structures (below 500 km) of flares are rarely observed and are accessible to only a few instruments world-wide.

Solar Flare Effects on the Earth’s Lower Ionosphere [PDF]
Solar Physics, 2021 Solar flares significantly impact the conditions of the Earth’s ionosphere. In particular, the sudden increase in X-ray flux during a flare penetrates down to the lowest-lying D-region and dominates ionization at these altitudes (≈60\documentclass[12pt ...

Operational solar flare prediction model using Deep Flare Net [PDF]
Earth, Planets and Space, 2021 We developed an operational solar flare prediction model using deep neural networks, named Deep Flare Net (DeFN). DeFN can issue probabilistic forecasts of solar flares in two categories, such as ≥ M-class and

Omori’s Law in the Occurrence of Solar Flare : Approach of Hybrid Model [PDF]
Iranian Journal of Astronomy and Astrophysics, 2020 Solar flares are large-scale phenomena that have a significant effect on theEarth’s climate. Using the solar flare time series from January 1, 2006 to July 21, 2016,we develop a complex network for predicting solar flares.
