Solar Activity Predictions for the Solar Activity Cycle

In the present work, the possibility of using relative sunspot numbers of the known solar cycles to predict the forthcoming solar activity of a progressing cycle is investigated, and solar activity of solar cycle 23 in the forthcoming several years is forecasted. The gross level (the sum of sunspot numbers of a cycle) of solar activity of cycle 23 is estimated to be 0.75 times as much as its neighboring cycle, cycle 22.
