We report on measurements of the solar surface differential rotation made from SOI/MDI full-disk Dopplergrams obtained once per minute during the 2-month Dynamics Program from 23 May through 26 July 1996. We infer the rotation profile both from the direct photospheric Doppler signal and also by tracking Doppler features (supergranules) across the solar disk. We study the rotation curve as a function of latitude, feature size, and tracking method, and look for global scale flows.

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.
