Änderungen der differentiellen Rotation und meridionale Bewegungen von Sonnenflecken 1940 bis 1968.
Abstract
Various methods of measuring solar activity are discussed with emphasis given to following identifiable objects such as sunspots over a period of time. A formula describes the rotation of sunspots for the period between 1940 and 1968, and the data for each year are divided within a seven year cycle. Mathematical formulas of rotation are also presented for the northern and southern hemispheres. Latitudinal movement of sunspots is investigated and compared to the method of Ward (1965). Differences in northern and southern hemisphere movement are considered.
