Abstract:
In this work we investigate a solar active region NOAA 11515 with flares and confirmed seismic activity. We focus on the evolution of photospheric magnetic fields obtained from SDO/HMI data. Time series of magnetograms allow the analysis of the evolution of magnetic features, i.e changes in the magnetic geometry and magnetic flux. Moreover, we follow the temporal evolution of white-light intensity to correlate the flaring emission with the magnetic dynamics and th helioseismic response. This study is intended to shed light on the evaluation of different hypothesis of sunquakes generation.
