Dynamics of Electric Current’s Parameters in Active Regions on the Sun and Their Relation to the Flare Index

Autor: Yu. A. Fursyak, A.S. Kutsenko, V. I. Abramenko

Publikováno v: Astrophysics. 63:260-273

Data from the Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO) on the components of the magnetic field vector in the photosphere for 39 active regions (AR) of the 24th solar activity cycle are used to calculate the

Possibilities for Estimating Horizontal Electrical Currents in Active Regions on the Sun

Autor: V. I. Abramenko, Yu. A. Fursyak

Publikováno v: Astrophysics. 60:544-552

Part of the “free” magnetic energy associated with electrical current systems in the active region (AR) is released during solar flares. This proposition is widely accepted and it has stimulated interest in detecting electrical currents in active

Sunspot groups with high flare activity: Specific features of magnetic configuration, morphology, and dynamics

Autor: Yu. A. Fursyak

Publikováno v: Geomagnetism and Aeronomy. 56:930-937

Specific features of the magnetic configuration, morphological structure, dynamics, and evolution of sunspot groups of the current (24th) cycle of solar activity with high flare activity are considered. The gradients of longitudinal magnetic fields a

X-class flares in the 24th solar activity cycle: Preflare and postflare conditions in the active region: Part 1. Analysis criteria and general comments

Autor: Yu. A. Fursyak

Publikováno v: Bulletin of the Crimean Astrophysical Observatory. 110:125-131

We analyzed the data on the flares of the X-ray class X in the 24th solar activity cycle. Several properties of the active regions (their morphological structure, the changes in the structure of the magnetic fields of spots, the evolution dynamics, e
