                         passed through a maximum. The maximum annual mean sunspot number 
                         was 157 for 1989. The maximum twelve-month running average was 
                         159, centered at July, 1989. For cycle 21, similar value was 165 
                         centered at December 1979. Thus, cycle 22 is slightly weaker than 
                         cycle 21. Schatten and Sofia (1987) had predicted a stronger cycle 
                         22 (170 +- 25) as compared to cycle 21 (140 +- 20). Predictions 
                         based on single variable analysis viz. Rz (max) versus aa (min) 
                         were 165 and came true. Predictions based on a bivariate analyses 
                         viz. Rz(max) versus aa (min) and Rz(min) were 130 and proved to be 
                         underestimates. Other techniques gave over or underestimates.",
