Statistical studies of low-power solar flares. Distribution of flares by area, brightness, and classes [PDF]
Solar-Terrestrial Physics, 2017 An electronic database has been created for 123801 solar flares that occurred on the Sun over the period from 1972 to 2010. It is based on catalogs of the Solar Geophysical Data (SGD) and Quarterly Bulletin on Solar Activity.

THE PROCESSES OF ENERGY RELEASE IN LOW-POWER SOLAR FLARES
Solar-Terrestrial Physics, 2019 Using flare patrol data for 1972–2010 [http://www.ngdc.noaa.gov/stp/space-weather/solar-data/solar-features/solar-flares/], we have conducted statistical studies of small solar flares.

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.

On the classifications of the solar active regions (ARs); Case study for solar cycles 23 and 24
Egyptian Journal of Remote Sensing and Space Sciences, 2018 The declining phase of solar cycle 23 is an important case of study. Many high energetic solar flares occurred in 2003. The occurrence of high energetic solar X-ray flares (X-type) is related to solar cycle’s phases and the state of the active regions ...

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.

Space Weather, 2023 Solar flares can severely disturb the Earth's ionosphere, leading to changes of atmospheric chemistry and degradation of Global Navigation Satellite System (GNSS) signals. The key to better assess these effects is to more accurately quantify the electron

Particle acceleration in the presence of weak turbulence at an X-type neutral point [PDF]
, 2012 We simulate the likely noisy situation near a reconnection region by superposing many 2D linear reconnection eigenmodes. The superposition of modes on the steady state X-type magnetic field creates multiple X- and O-type neutral points close to the ...

Statistical studies of duration of low-power solar flares
Solar-Terrestrial Physics, 2018 This paper is a sequel to papers dealing with time parameters of solar flares in the Hα line. Using data from the international flare patrol for 1972–2010, we have determined the mean duration of flares of different importance and classes of area.
