The observed kink motion. The left hand column panel shows time-distance diagrams from various cross-cuts. Each cross-cut shown is separated by 800 km, with the lowest cross-cut on the top row. The right hand column shows the results of the Gaussian fits (crosses) with the σ error bars on the measured position. The solid line is the result of the damped sinusoidal fit. The given distance corresponds to the position along the cross-cut and the time is seconds from 01:20:51 UT.
