Do polar faculae terminate or commence an extended cycle of solar activity?

From the local as well as from the global points of view, polar magnetic fields are formed from successively developed trailing polarity fields expelled from the main activity zone. Polar faculae observed during the 20th and the 21st cycles of activity fill in the areas covered by the most intense unipolar fields distributed in the convection network. These polar regions formed from magnetic fields of an old activity cycle are sharply separated from low-latitude magnetic fields and from fields developed by a new cycle of activity. The polarity distribution in polar faculae seems to follow from unipolarity of their magnetic fields - the prevailing polarity becomes the main leading polarity. The greatest part of the main activity zone, the most intense faculae shifting equatorwards are connected with the zone of the prevailing leading polarity magnetic fields. Some of these faculae - the weak and inhomogeneously distributed ones, bordering the main faculae butterflies polewards - are related again to the trailing polarity fields shifting polewards. The main characteristic of the latitudinal distribution of solar faculae is the existence of their two latitudinal types: the polar faculae shifting polewards are related to the trailing polarity fields of the old cycle, the faculae of the main activity zone shifting equatorwards are related mainly (from the global point of view) to the leading polarity fields, and their activity ends several years earlier than that of the polar ones. The polar faculae with their magnetic fields represent the last phase of the magnetic activity cycle lasting 15-17 years. (author). 6 figs., 21 refs
