A Prediction of the Maximum of Sunspot Number And Its Maximum Epoch in Cycle 22

Using the characteristics of the odd-even order combinations of solar cycles,it is predicted that the maximum value of Lhc sunspot number in Cycle 22 will be less than that in Cycle 21.The maximum smoothly mean of the sunspot numbers will lie between l05 and 122 by rough estimate.The Cycle 22 will reach its maximum during the second half of 1991.The probabilities of that the Cycle 22 belong to high,middle or low cycle are discussed.
