Statistical analysis of the total magnetic flux decay rate in solar active regions
Andrei A. Plotnikov, Valentina I. Abramenko, Alexander S. Kutsenko
We used line-of-sight magnetograms acquired by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory to derive the decay rate of total unsigned magnetic flux…
The rotation rate of solar active and ephemeral regions -- II. Temporal variations of the rotation rates
Alexander S. Kutsenko, Valentina I. Abramenko, Daria V. Litvishko
Systematic studies of the rotation rate of sunspot groups using white-light images yield controversial results on the variations of the rotation rate: sunspot groups were found to…
A statistical study of magnetic flux emergence in solar active regions prior to strongest flares
Alexander S. Kutsenko, Valentina I. Abramenko, Andrei A. Plotnikov
Using the data on magnetic field maps and continuum intensity for Solar Cycles 23 and 24, we explored 100 active regions (ARs) that produced M5.0 or stronger flares. We focus on th…
On the possibility to probe the flare productivity of an active region on the early stage of emergence
Alexander S. Kutsenko, Valentina I. Abramenko, Olga K. Kutsenko
A long-standing problem is to predict the future flare productivity of an active region (AR) when it is on the stage of early emergence. The aim of this study is to probe two param…
The rotation rate of solar active and ephemeral regions -- I. Dependence on morphology and peak magnetic flux
Alexander S. Kutsenko
Using magnetic field maps acquired by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory we measured rotation rates of 864 active and 322 ephemeral region…
Distributed Electric Currents in Solar Active Regions
Yuriy A. Fursyak, Alexander S. Kutsenko, Valentina I. Abramenko
Using magnetographic data provided by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory, we analyzed the structure of magnetic fields and vertical electr…
