AB: A statistically robust technique for determining motion perpendicular to the line of sight from a sequence of solar magnetograms is required for understanding the physics of active regions and related phenomena. However, Local Correlation Tracking (LCT), the de-facto standard for estimating motion in solar image sequences, is inconsistent with the magnetic induction equation and mathematically inappropriate for tracking magnetic elements. A new technique is presented that incorporates the magnetic induction equation directly into the analysis. This method represents a generalization of established wavelet interferometric techniques, developed for the analysis of turbulence in space-craft data, to the multi-point data represented by magnetograms.
