Solar Latitudinal Distribution of Solar Flares around the Sun and Their Association with Forbush Decreases during the Period of 1986 to 2003 [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2005
Solar flare events of high importance were utilised to study solar latitudinal frequency distribution of the solar flares in northern and southern hemisphere for the solar cycle 22 to recent solar cycle 23.

Performance of radio-based detection for operational monitoring of M5+ class solar flares

open access: yesJournal of Space Weather and Space Climate
Early detection of major solar flares is critical due to their potential to disturb radar and radio systems. Typically, soft X-ray flux is used to monitor and classify solar flares, but since this flux has to be measured in space, it means that its ...

Solar Flares [PDF]

open access: yes, 2011
Solar flares accelerate both ions and electrons to high energies, and their X-ray and gamma-ray signatures not only probe the relationship between their respective acceleration, but also allow for the measurement of accelerated and ambient abundances ...

Detecting the Sun’s active region using image processing techniques

open access: yesPhysical Sciences and Technology, 2021
The term ‘space weather’ refers to adverse conditions on the Sun that could affect the structures of space or terrestrial technology and risk human health or life. Flares produce effects that span the electromagnetic spectrum.

Ion Acceleration in Solar Flares

open access: yes, 1996
Solar flares are among the most energetic and interesting phenomena in the Solar system, releasing up to 1032 ergs of energy on timescales of several tens of seconds to several tens of minutes. Much of this energy is in the form of suprathermal electrons

The Occurrence of Powerful Flares Stronger than X10 Class in Solar Cycles

open access: yesThe Astrophysical Journal Letters
Solar flares stronger than X10 (S-flares,  >X10) are the highest-class flares that significantly impact on the Sun's evolution and space weather. Based on observations of Geostationary Orbiting Environmental Satellites at soft X-ray wavelength and the ...

Overview of solar flares

open access: yes, 2004
This chapter reviews the physics of solar flares, with special emphasis on the past decade. During this decade first Yohkoh and then TRACE have drastically improved our observational capabilities for flares, with contributions also from the essentially ...

Rapid fluctuations in solar flares [PDF]

open access: yes, 1986
Study of rapid fluctuations in the emission of radiation from solar flares provides a promising approach for probing the magneto-plasma structure and plasma processes that are responsible for a flare.

Excitation of solar p-mode oscillations by flares

open access: yes, 2003
Solar flares release large amounts of energy at different layers of the solar atmosphere. It is, therefore, expected that major flares would be able to excite waves, thereby affecting the p-mode oscillation characteristics. From the analysis of MDI data,
