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. Using G-band and Stokes-V data obtained with Hinode Solar Optical Telescope, we study the sunspot motion and flow fields associated with the 2006 December 13 X3.4 flare in NOAA AR 10930. We calculate the centroids of the delta spot umbrae lying in opposite magnetic polarities, and use various local correlation tracking techniques to derive the photospheric flow fields of the AR. 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.
