The very latest sunspot predictions from NOAA for cycle 24 make rather depressing reading showing a 95% probability of a peak smoothed sunspot number of just 91.8 in June 2013. By this autumn we should see counts in the mid 40s and the following autumn around 75. 10m transatlantic openings should be common again from this autumn, but the low sunspot peak suggests 6m openings will be much less frequent than in recent cycles. So, in my lifetime it is unlikely I'll ever see again the halcyon days of the peak of 1957-9 when conditions were remarkable.
