Chromospheric signatures of small-scale flux emergence as observed with NST and Hinode instruments
V. B. Yurchyshyn, P. R. Goode, V. I. Abramenko +4
With the ever increasing influx of high resolution images of the solar surface obtained at a multitude of wavelengths, various processes occurring at small spatial scales have beco…
Intermittency Spectra of the Magnetic Field in Solar Active Regions
Valentyna Abramenko, Vasyl Yurchyshyn
We present results of a study of intermittency and multifractality of magnetic structures in solar active regions (ARs). Line-of-sight magnetograms for 214 ARs of different flare p…
Spectrum of Magnetic Dissipation and Horizontal Electric Currents in the Solar Photosphere
Valentyna Abramenko
A proxy for horizontal electric currents in the solar photosphere was suggested. For a set of evolving active regions (ARs) observed with {\it Solar and Heliospheric Observatory (S…
Topological changes of the photospheric magnetic field inside active regions: a prelude to flares
L. Sorriso-Valvo, V. Carbone, V. Abramenko +5
The observations of magnetic field variations as a signature of flaring activity is one of the main goal in solar physics. Some efforts in the past give apparently no unambiguous o…
