Abstract By superposing data for many sunspot groups measured on the Mount Wilson white-light plate collection, the authors demonstrate that differential rotation, about equal to the ambient rate, occurs between sunspots within the group. It is also shown that the relative motions of leader and follower sunspots can be characterized primarily as a simple expansion of the group along its major axis, with very little rotation of the pattern about group center.
