Solar activity - a second peak?

Looking at the sunspot and solar flux levels in the last month, it looks like we are seeing evidence of a second peak to cycle 24.  Whether it exceeds the peak of November 2011 remains to be seen.  As the slide down from the peak(s) is slower than the rise towards the peak(s), we can expect reasonable HF conditions for several more years yet before we return to the quiet years when activity on 12 and 10m is very low indeed.
