NOAA’s Space Weather Prediction Center today posted its monthly update of the ongoing sunspot cycle of the Sun. As I do every month, I am posting this graph, which you can see below the fold.

June sunspot graph

As the graph clearly shows, the Sun’s sunspot activity continues to be far below the prediction (indicated by the red line). In June activity dipped slightly, returning to the numbers seen in March. This is not what we should be seeing at this point in the ramp up to solar maximum next year. Rather than dipping, sunspot activity should be rising.

The trend, as indicated by the bright blue line, continues to suggest that the peak, predicted for the spring of 2013, is going to be far less than predicted. And the peak, as predicted, would be the weakest maximum in a hundred years. If that peak instead turns out to be as weak as the trend line suggests, it would be weakest in centuries, since the long Maunder Minimum of the 1600s, when there were no sunspots for decades.
