[2.64] Preliminary SoHO/MDI Observations of Supergranular Evolution

G. W. Simon (AF/PL/GPSS), L. H. Strous, S. Matt (NSO/SP), A. M. Title, C. J. Schrijver (SLISR)

We present preliminary results of a study into the evolution of supergranules, using data from SoHO/MDI. We discuss the supergranular size spectrum, lifetimes, and topological evolution. We compare structures of supergranular size visible in high-resolution SoHO/MDI dopplergrams and in divergence maps derived from tracking of features in dopplergrams.

This work was supported by NASA Grant NAG5-3077 at Stanford and Lockheed Martin, and by AFOSR and the Fellows Program of AF Phillips Lab at NSO/SP.
