Severny (1969) used a technique which enables the Sun to be observed like a magnetic star. Because of rotation, different sides of the Sun are visible at different times. A curve of variable magnetic field is obtained. During nearly three periods of rotation the Sun appears to be a quadrupole magnetic rotator. Generally, the integrated field of sunspots seems to be opposite to the field of the Sun as a whole. The curve seemed to remain similar throughout the year 1968.
