| Abstract: | On the basis of the data on prominence areas for 1880–1976 and positions of the boundary background magnetic field for 1955–1982 it is shown that the maximum development of prominences and their poleward migration, accompanied by the magnetic field reversal, concides with the first maximum of the 11-year solar cycle, which is characterized by an enhancement of solar activity at all latitudes. The second maximum is an increase of all features, including prominences but in the low latitudes only. That prominence zone migrates poleward in the following 11-year solar cycle. |
