Abstract:
Sun quakes are one of the most puzzling phenomena of the Sun. They are produces by solar flares, but the driving mechanism is not fully understood yet. In this paper we will study the behaviour of the coronal loops of acoustically active flares, as they are seen in X-ray and the temporal profile of the associated photospheric magnetic field for two of these active flares from 15 August 2004 and 13 September 2005.
