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…
Magnetic fluxes of solar active regions of different magneto-morphological classes: I. Cyclic variations
Valentina I. Abramenko, Regina A. Suleymanova, Anastasija V. Zhukova
Data for 3046 solar active regions (ARs) observed since May 12, 1996 to December 27, 2021 were utilized to explore how the magnetic fluxes from ARs of different complexity follow t…
Synthetic solar cycle for active regions violating the Hale's polarity law
A. Zhukova, A. Khlystova, V. Abramenko +1
Long observational series for bipolar active regions (ARs) provide significant information about the mutual transformation of the poloidal and toroidal components of the global sol…
Signature of the turbulent component of solar dynamo on active region scales and its association with flaring activity
Valentina I. Abramenko
Obtaining observational evidence of the turbulent component of solar dynamo operating in the convective zone is a challenging problem because the dynamo action is hidden below the…
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…
