Characteristics of flight delays during solar flares [PDF]
Scientific Reports, 2023 Solar flares are one of the severest solar activities that have important effects on near-Earth space. Previous studies have shown that flight arrival delays increase as a result of solar flares, but the intrinsic mechanism behind this relationship is ...

Probability Distribution Functions of Solar and Stellar Flares
Physics, 2022 The paper studies the soft X-ray data of solar flares and found that the distribution functions of flare fluence are successfully modeled by tapered power law or gamma function distributions whose power exponent is slightly smaller than 2, indicating ...

Operational prediction of solar flares using a transformer-based framework. [PDF]
Sci Rep, 2023 Solar flares are explosions on the Sun. They happen when energy stored in magnetic fields around solar active regions (ARs) is suddenly released. Solar flares and accompanied coronal mass ejections are sources of space weather, which negatively affects a

Integration of solar flare and coronal mass ejection event dataHarvard Dataverse [PDF]
Data in BriefSolar 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

The 6 September 2017 X-Class Solar Flares and Their Impacts on the Ionosphere, GNSS, and HF Radio Wave Propagation. [PDF]
Space Weather, 2018 On 6 September 2017, the Sun emitted two significant solar flares (SFs). The first SF, classified X2.2, peaked at 09:10 UT. The second one, X9.3, which is the most intensive SF in the current solar cycle, peaked at 12:02 UT and was accompanied by solar ...

Coronal Elemental Abundances During A-Class Solar Flares Observed by Chandrayaan-2 XSM [PDF]
Solar Physics, 2023 The abundances of low first ionization potential (FIP) elements are three to four times higher in the closed loop active corona than in the photosphere, known as the FIP effect.

The origin of underdense plasma downflows associated with magnetic reconnection in solar flares [PDF]
Nature Astronomy, 2021 Magnetic reconnection is a universal process that powers explosive energy-release events such as solar flares, geomagnetic substorms and some astrophysical jets.

Predicting Solar Flares Using CNN and LSTM on Two Solar Cycles of Active Region Data [PDF]
Astrophysical Journal, 2021 We consider the flare prediction problem that distinguishes flare-imminent active regions that produce an M- or X-class flare in the succeeding 24 hr, from quiet active regions that do not produce any flares within ±24 hr.

Effect of solar flares on 54Mn and 57Co radioactive decay constants performance [PDF]
Nuclear Technology and Radiation Protection, 2021 Changes in radioactive decay rates due to solar flares have attracted increasing scientific attention in recent decades. In previous studies we demonstrated that solar flares cause changes in the decay rate of 241Am, 222Rn, and 232Th. The change
