Confinedness of an X3.1 class solar flare occurred in NOAA 12192: Analysis from multi-instruments observations
N. Vasantharaju, F. Zuccarello, F. Ferrente +1
The non-association of coronal mass ejections with high energetic flares is sparse. For this reason, the magnetic conditions required for the confinedness of major flares is a topi…
Restoring process of sunspot penumbra
P. Romano, M. Murabito, S. L. Guglielmino +2
We describe the disappearance of a sector of sunspot penumbra and its restoring process observed in the preceding sunspot of active region NOAA 12348. The evolution of the magnetic…
Height dependence of the penumbral fine-scale structure in the inner solar atmosphere
Mariarita Murabito, I. Ermolli, F. Giorgi +6
We studied the physical parameters of the penumbra in a large and fully-developed sunspot, one of the largest over the last two solar cycles, by using full-Stokes measurements take…
The 17 February 2013 sunquake in the context of the active region's magnetic field configuration
Lucie M. Green, Gherardo Valori, Francesco P. Zuccarello +3
Sunquakes are created by the hydrodynamic response of the lower atmosphere to a sudden deposition of energy and momentum. In this study we investigate a sunquake that occurred in N…
The Signature of Flare Activity in Multifractal Measurements of Active Regions Observed by SDO/HMI
F. Giorgi, I. Ermolli, P. Romano +3
Recent studies indicate that measurements of fractal and multifractal parameters of active regions (ARs) are not efficient tools to discriminate ARs on the basis of the flare activ…
Vortex and sink flows in eruptive flares as a model for coronal implosions
Francesco P. Zuccarello, Guillaume Aulanier, Jaroslav Dudík +3
Eruptive flares are sudden releases of magnetic energy that involve many phenomena, several of which can be explained by the standard 2D flare model and its realizations in three-d…
