Closeup of the sunspot prediction for cycle 25. The thick (thin) black curve shows the original 13-month smoothed (unsmoothed monthly) SSN. The red curves show the optimal 4-parameter fits to the SSN cycles. The green curves show the sunspot cycles predicted using the precursor values. The dark and light blue shadings show the 1- and 2-standard deviation ranges based on the ensemble of SSN predictions. The magenta curve shows the prediction for cycle 25 and the dashed purple curve (and yellow uncertainty range) shows the cycle 25 prediction according to the international sunspot prediction panel obtained from the Space Weather Prediction Center
