| Abstract: |
A detailed magnetoseismic analysis of the active region AR10720
on 15 January 2005 is presented. The X1.2 solar flare generated
the most powerful seismic emission discovered to date. We study
the configuration of the l-o-s magnetic field lines in
the quaked area, using extrapolations of the photospheric
magnetic field (Sudol & Harvey 2005). Temporal properties of
the 6 mHz egression power maps in the area of interest are also
analysed. We then describe a number of mechanisms believed to
trigger a seismic source during a flare and discuss the
likelihood that one of these would generate a sunquake. For
this particular sunquake the McClymont effect does not seem to
explain the high seismicity of the region. |
