Investigations based on independent observational materials and carried out by different authors show that sunspot groups display a latitudinal drift curve, the shape of which depends on phase in the solar cycle. Ward has tried to disprove this. His conclusions are based on ignorance of work done pr

Using new measurements of positions of individual sunspots and sunspot groups obtained from 62 years of the Mt. Wilson white-light plate collection, we have recomputed the correlation between longitude and latitude motion. Our results for groups are similar to those of Ward (1965a) computed from the
From high precision computer controlled tracings of bright Ca+-mottles we investigated differential rotation, meridional and random motions of these chromospheric fine structures. The equatorial angular velocity of the Ca+-mottles agrees well with that of sunspots (14.~ per day, sidereal) and is 5 7
