Solar Flares Complex Networks [PDF]
The Astrophysical Journal, 2017 We investigate the characteristics of the solar flares complex network. The limited predictability, non-linearity, and self-organized criticality of the flares allow us to study systems of flares in the field of the complex systems. Both the occurrence time and the location of flares detected from January 1, 2006 to July 21, 2016 are used to design the

Initial Observations of Sunspot Oscillations Excited by Solar Flare [PDF]
, 2007 Observations of a large solar flare of December 13, 2006, using Solar Optical Telescope (SOT) on Hinode spacecraft revealed high-frequency oscillations excited by the flare in the sunspot chromosphere. These oscillations are observed in the region of strong magnetic field of the sunspot umbra, and may provide a new diagnostic tool for probing the ...

Is FLARE for Solar flare? [PDF]
PoS (Proceedings of Science), HEP 2005, 336, p.1-6, 2005 The Fermi Lab Liquid ARgon experiment, FLARE, a huge neutrino argon-liquid project detector of 50 kt mass, might in a near future enlarge the neutrino telescope accuracy revealing in detail solar, supernova, atmospheric as well as largest solar flares neutrino.

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.

Statistical analysis for EUV dynamic spectra and their impact on the ionosphere during solar flares
Earth, Planets and Space, 2023 The X-rays and extreme ultraviolet (EUV) emitted during solar flares can rapidly change the physical composition of Earth’s ionosphere, causing space weather phenomena.

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.

INCREASES IN SCR ENERGETIC PROTON FLUXES ON EARTH AND THEIR RELATION TO SOLAR SOURCES
Solar-Terrestrial Physics, 2020 Logachev catalog data for solar cycle 23 has been used to study the dependence of measured increases in solar cosmic rays (SCRs) on solar perturbations. The efficiency of recording the SCR increases, driven by proton acceleration in the corona, on Earth ...

Change ratios of magnetic helicity and magnetic free energy during major solar flares [PDF]
, 2023 Magnetic helicity is an important concept in solar physics, with a number of theoretical statements pointing out the important role of magnetic helicity in solar flares and coronal mass ejections (CMEs). Here we construct a sample of 47 solar flares, which contains 18 no-CME-associated confined flares and 29 CME-associated eruptive flares. We calculate

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.
