                         the maxima Rz(max)of smoothed sunspot numbers reached values of 
                         similar to140 by cycle 0-1 (similar to1750)and then had long-term 
                         fluctuations (high values for 3-5 cycles, followed by low values 
                         for 3-5 cycles, differing by as much as 50 units), on which random 
                         fluctuations were superposed. There is some indication of a 
                         similar to100-year oscillation that might have peaked near cycle 
                         20 at Rz( max) values near similar to150. If this oscillation 
                         persists, the cycles in the next 50 years or so may have lower and 
                         lower R(max), perhaps dropping below 100, and recovering 
                         thereafter. The aa(min)values, and to a lesser degree, the Rz(min) 
                         values, are also expected to follow the same pattern.",
