Observations of the formation of a proto-spot in a pre-existing field environment
Mariarita Murabito, Ilaria Ermolli, Salvo L. Guglielmino +2
Bipolar emerging flux regions (EFRs) form active regions (ARs) that generally evolve in a pre-existing magnetic environment in the solar atmosphere. Reconfiguration of the small- a…
Analysis of full-disc H alpha observations: Carrington maps and filament properties in 1909-2022
Theodosios Chatzistergos, Ilaria Ermolli, Dipankar Banerjee +14
Full disc observations of the Sun in the H line provide information about the solar chromosphere and in particular about the filaments, which are dark and elongated features tha…
Observations of the chromospheric Evershed flow of sunspot penumbra
Paolo Romano, Francesco Schillirò, Mariachiara Falco
The sunspot penumbra is usually observed in the photosphere and it is of particular interest for its magneto-convection which seems to transport the heat from the top of the convec…
Segmentation of spectroscopic images of the low solar atmosphere by the Self Organizing Map technique
Schillirò Francesco, Romano Paolo
We describe the application of Semantic Segmentation by using the Self Organizing Map technique to an high spatial and spectral resolution dataset acquired along the H line at 6…
Long-term optical monitoring of the solar atmosphere in Italy
S. L. Guglielmino, I. Ermolli, P. Romano +8
Probably, the long-term monitoring of the solar atmosphere started in Italy with the first telescopic observations of the Sun made by Galileo Galilei in the early $17^{\mathrm{th}}…
Observational evidence of torus instability as trigger mechanism for coronal mass ejections: the 2011 August 4 filament eruption
Francesco P. Zuccarello, Daniel B. Seaton, Marilena Mierla +4
Solar filaments are magnetic structures often observed in the solar atmosphere and consist of plasma that is cooler and denser than their surroundings. They are visible for days --…
Magnetic evolution of superactive regions. Complexity and potentially unstable magnetic discontinuities
S. Criscuoli, P. Romano, F. Zuccarello +1
In this work, we have studied the temporal evolution of some properties of a sample of superactive regions with the aim to single out the most significant for flare activity foreca…
