Abstract:

The attempts to investigate patterns of motions of main spot components and small pores in complex sunspot groups were continued. The data discussed stem mainly from observations at Hvar/HR and Tatranska Lomnica/SK. Two historic collections of photographics plates are included: The plate archives of the former Fraunhofer Institut and that of photographic plates taken at Skalnate Pleso/SK.
