The recent Solar Cycle is represented in several ways. At the top is the Sunspot Number, in the middle, the F10.7cm Radio Flux, and at the bottom, the Ap Index (a measure of geomagnetic activity) history.
In all of the plots, the black line represents the monthly averaged data and the blue line represents a 13-month smoothed version of the monthly averaged data. For the Sunspot Number and F10.7cm, the forecast for the rest of the solar cycle is given by the red line.
