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
The question is studied whether the one-year solar oscillation found by V. F. Chistyakov for the years 1965-1973 can be traced in the observations of sunspots of 1874-1971 published by Greenwich Observatory. The result is negative. But the study leads to the following two conclusions: (1) The averag
We report measurements of the sunspot rotation rate at high sunspot latitutdes for the years 1966-1968. Ten spots at [latitude[-> 28 deg were found in our Mees Solar Observatory Ha patrol records for this period that are suitable for such a study. On the average we find a sidereal rotation rate of 1
