Forecasting Solar Flares Using Magnetogram-based Predictors and Machine Learning [PDF]
Solar Physics, 2018 We propose a forecasting approach for solar flares based on data from Solar Cycle 24, taken by the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) mission.

Predicting Solar Flares Using a Long Short-term Memory Network [PDF]
Astrophysical Journal, 2019 We present a long short-term memory (LSTM) network for predicting whether an active region (AR) would produce a ϒ-class flare within the next 24 hr. We consider three ϒ classes, namely ≥M5.0 class, ≥M class, and ≥C class, and build three LSTM models ...

Solar flares at submillimeter wavelengths [PDF]
The Astronomy and Astrophysics Review, 2013 We discuss the implications of the first systematic observations of solar flares at submillimeter wavelengths, defined here as observing wavelengths shorter than 3 mm (frequencies higher than 0.1 THz). The events observed thus far show that this wave band requires a new understanding of high-energy processes in solar flares.

Predicting Solar Flares with Machine Learning: Investigating Solar Cycle Dependence [PDF]
Astrophysical Journal, 2019 A deep learning network, long short-term memory (LSTM), is used to predict whether an active region (AR) will produce a flare of class Γ in the next 24 hr. We consider Γ to be ≥M (strong flare), ≥C (medium flare), and ≥A (any flare) class. The essence of

International Astronomical Union Colloquium, 1995 AbstractThere are many types of solar flare, but the classic type is a two-ribbon flare with three phases — a preflare phase, a rise phase and a main phase. The properties of these phases are described, together with some recent observational advances in understanding the conditions for solar flares.

Comparison of VLF Signal Responses to Solar Flares along Daytime and Nighttime Propagation Paths
Remote Sensing, 2023 Solar flares have a severe impact on the near-earth space environment, during which the VLF signals observed by the ground-based instrument exhibit abnormal changes.

Solar Radio Bursts with Spectral Fine Structures in Preflares [PDF]
, 2014 A good observation of preflare activities is important for us to understand the origin and triggering mechanism of solar flares, and to predict the occurrence of solar flares.

Using Machine Learning Methods to Forecast if Solar Flares Will Be Associated with CMEs and SEPs [PDF]
Astrophysical Journal, 2018 Among the eruptive activity phenomena observed on the Sun, those that threaten human technology the most are flares with associated coronal mass ejections (CMEs) and solar energetic particles (SEPs).

A Database of Magnetic and Thermodynamic Properties of Confined and Eruptive Solar Flares
The Astrophysical Journal, 2023 Solar flares sometimes lead to coronal mass ejections that directly affect Earth's environment. However, a large fraction of flares, including on solar-type stars, are confined flares.
