The N-S drift of sunspot groups has been studied in a different way than previously, using positions of recurrent groups of the years 1874-1976. The existence of the meridional motions, the general shape of the drift curves, and the dissimilarity between these curves around sunspot maxima and minima

Using two original copies of Hevelius' 'Selenographia' and reducing spot positions with two different methods, we found that the solar angular rotation velocity at the beginning of the Maunder minimum was about the same as today. The gradient of the differential rotation was slightly steeper than gi

The flux density of a noise storm continuum is known to depend on importance parameters of the associated sunspot group, e.g., its total areaA. A study of the continua at 287, 234, 113, and 64 MHz, however, reveals in case of the two cycles Nos. 20 and 21 that the radiation signatures of sunspot gro
