Scientific paper

The paper presents an analysis of Greenwich sunspot data for cycle No. 18 which shows: (1) higher rotation rates for the southern sunspot belt than for the northern belt, (2) lower rotation rates and a tendency to a more rigid rotation for greater sunspot groups, (3) lower rotation rates and a tendency to a more rigid rotation for older sunspot groups, (4) no dependence of rotation rates on the lifetime of sunspot groups, (5) a tendency to a more rigid rotation at the activity minimum. It is noted that results Nos. 2, 3, and 5 could be interpreted in terms of the evolution and interplay of the active regions, as the regions age. Finally, if it is assumed that the sunspot group life-time is a function of their depth in the solar atmosphere, result No. 4 shows that the rotation rates do not depend on the depth.
