The 'period-growth dichotomy' of the solar cycle predicts that cycle 21, the present solar cycle, will be of long duration (> 133 mo), ending after July 1987. Bimodality of the solar cycle (Le., cycles being distributed into two groups according to cycle length, based on a comparison to the mean cyc
Predicted values of some main indices of solar activity for the 21st solar cycle are given. The epoch of maximum of solar activity has been placed in 1980.8 + 0.1. The predicted peak values of the relative sunspot numbers published by other authors are also given.
Short-term variations ot the last solar activity cycle were studied by the flare and coronal indices using Gleissberg method. Systematic short-term variations are found from their course during the 21st solar activity cycle. Comparison of their autocorrelograms constructed by the new set of data obt
