Looking at relationships between terminator separation and sunspot cycle amplitudes. Linear regressions of the terminator separation versus (comparison 1; top panel) intermediate cycle sunspot maximum and (comparison 2; bottom panel) the following sunspot cycle maximum. The \(1\sigma \) (68%) confidence interval as well as the \(1\sigma \) (68%) and \(2\sigma \) (95%) prediction intervals are shown. The predicted terminator separation for SC24 is shown in both panels, which along with the regression line results in a prediction for the amplitude of SC25 in panel (b) that is significantly higher than the consensus prediction of the SC25PP (magenta bar). The black horizontal line in the top panel is the mean of the SSN maximum, while the dashed and dotted blue lines in the bottom panel are the 68% and 95% prediction interval boundaries for the SC25 prediction, respectively.
