In the 1990s, solar physicists, Penn and Livingston, called for a long decline in solar activity. This is the case and it is nice to see such work confirmed by events. Solar Cycles # 23 and 24 are the weakest since the early 1900s. The current run of consecutive Spotless Days is out to 33, or 75%, for the year.
The following table shows the record back to the minimum of Solar Cycle # 23 when the count was at 268 days, or 73%, for 2008.
