Anatomy of a solar flare: Part I. The solar quake measurements of the December 14, 2006 X-class flare with GONG, Hinode and RHE View all abstracts by submitter

Some of the most challenging observations to explain in the context of existing flare models are those related to the lower atmosphere and below the solar surface. Such observations, including changes in the photospheric magnetic field and seismic emission, indicate the poorly understood connections between energy release in the corona and its impact in the photosphere and the solar interior. Using data from Hinode, TRACE, RHESSI and GONG we study the temporal and spatial evolution of the 14 December 2006 X-class flare in the chromosphere, photosphere and the solar interior. We report for the first time the detection of a solar quake using time-distance methods applied to GONG data. We then investigate the connections between the emission at various atmospheric depths, with an emphasis on determining the origin of the acoustic responses observed with the GONG data. We report the horizontal displacements observed in the photosphere linked to the timing and locations of the solar quakes associated with this flare, their vertical and horizontal displacement velocities at different atmospheric depths and their implications for models developed for the interpretation of these observations reported in Part II.
