"A few prediction methods have been developed based on the precursor technique which is found to be successful for forecasting the solar activity," researchers in India report.
"Considering the geomagnetic activity aa indices during the descending phase of the preceding solar cycle as the precursor, we predict the maximum amplitude of annual mean sunspot number in cycle 24 to be 111 +/- 21. This suggests that the maximum amplitude of the upcoming cycle 24 will be less than cycles 21-22," wrote N.J. Bhatt and colleagues.
The researchers concluded: "Further, we have estimated the annual mean geomagnetic activity aa index for the solar maximum year in ...
