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…
Magnetic Power Spectra of Emerging Active Regions
Olga K. Kutsenko, Alexander S. Kutsenko, Valentina I. Abramenko
Magnetic field data provided by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory were utilized to explore the changes in the magnetic energy of four act…
Extended statistical analysis of emerging solar active regions
A. S. Kutsenko, V. I. Abramenko, A. A. Pevtsov
We use observations of line-of-sight magnetograms from Helioseismic and Magnetic Imager (HMI) on board of Solar Dynamics Observatory (SDO) to investigate polarity separation, magne…
Intermittency spectra of current helicity in solar active regions
A. S. Kutsenko, V. I. Abramenko, K. M. Kuzanyan +2
We analyse the spatial distribution of current helicity in solar active regions. A comparison of current helicity maps derived from three different instruments (Helioseismic and Ma…
