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…
Observational Evidence of a Flux Rope within a Sunspot Umbra
Salvo L. Guglielmino, Paolo Romano, Francesca Zuccarello
We observed an elongated filamentary bright structure inside the umbra of the big sunspot in active region NOAA 12529, which differs from the light bridges usually observed in suns…
Polarised kink waves in magnetic elements: evidence for chromospheric helical waves
Marco Stangalini, Fabio Giannattasio, Robertus Erdélyi +6
In recent years, new high spatial resolution observations of the Sun's atmosphere have revealed the presence of a plethora of small-scale magnetic elements down to the resolution l…
Observation of a 3D magnetic null point
P. Romano, M. Falco, S. L. Guglielmino +1
We describe high resolution observations of a GOES B-class flare characterized by a circular ribbon at chromospheric level, corresponding to the network at photospheric level. We i…
