Observation of Solar Differential Rotation with the Aid of Magnetic Tracers
Abstract
We tried to search for the manifestation of differential rotation in the distribution of weak remnants of magnetic fields measured with a very low resolution. We found that, during the periods of low solar activity and in parts of the solar photosphere with smaller density of new magnetic flux sources, it was possible to observe the distribution of magnetic tracers in the form of differential rotation parabolas which increase their curvature from one rotation to the next. The obtained differential rotation rates are not far from those given by highly averaged sunspot data or by the daily magnetic fields. The characteristic differential rotation parabolas as well as specific cellular-like features disturbing their smooth patterns are always formed from fields of one main polarity, the sign of which depends on the phase of the activity cycle.
