2008 in Top Five Years for Sunspotless Days Last Century – Could End up #3 or Even 2
From ICECAP, November 30, 2008
By Joseph D’Aleo, CCM, AMS Fellow
One of our loyal Canadian Icecap readers asked us to comment on the fact we are now at the end of November, in the top five years with the most sunspotless days the last century and heading towards a #3 or even #2 finish depending on how many spotless days we have in December. Here is a comparison of monthly spotless days in this cycle 23 minimum (red) versus the last cycle 22 minimum in the mid 1990s (blue).

Notice how quiet and prolonged this minimum has been compared to the last minimum. As of November 30, we have had 236 spotless days in 2008, enough to put us in 5th place. With just half a dozen spotless days, we will exceed #3 1954. If we exceed November’s 14 spotless days, we will be in a virtual tie for second place with 1912 behind 1913.

Notice how 2007 and 2008 are both in the top 10.
So far in minimum after cycle 23, we have had 481 spotless days, the most since cycles 14-16, in the early 1900s. Note in cycle 14, three years came in the top 10 for spotless days, 1911, 1912, 1913. This is the second year in this cycle in the top 10. 1912 was the second high spotless year after cycle 14.
See this story in the Toronto Star by Adam Mayers from February 2007, during the very cold and record snowy 2007/08 Toronto winter. It talks about 1911/12 winter, the worst winter of the century for that city.
“It may seem cold this week, but it is nothing, nothing, compared with the winter of 1912, a year that remains in the record books as the worst winter of the past 100 years. By mid-January, it was so cold Toronto harbour was frozen solid. By early February, the near-shore lake ice was a metre thick, and you could skate from Toronto to Hamilton if you had the time. By the middle of the month, everyone was taking bets on whether the lake was frozen over. By month-end, it was. It was the rumour that the lake ice was finally solid from Toronto to Rochester that brought a huge crowd to Sunnyside Park on the afternoon of Feb. 11, 1912. They wanted to witness what the Star called a once-in-a-lifetime experience, “a spectacle they had never seen before and may never witness again.”
