Study of Sunspot Motion Associated with the 2006 Dec. 13 X3.4 Flare Shuo Wang Advisor: Chang Liu Haimin Wang
Introduction Evolution of sunspot structure and photospheric magnetic fields are important to understand how the flare energy is built up and released. With high-resolution optical data, it is possible to examine in details the optical motions on the photosphere and its relationship to the flaring process.
Plan to do derive the photospheric flow fields Local Correlation Tracking (LCT) Differential Affine Velocity Estimator (DAVE)
We mainly concern ourselves with the temporal evolution of these physical quantities, careful study of which can help to advance our understanding of flare trigger mechanism and the photospheric response to the flare energy release.
