. Gotta run quick... A short update on the Sun. Right now we have been 30 days without a sunspot. Thus, the length of the solar minimum has been extended for another month. I have addressed the significance of this as far as the likelihood of much cooler temperatures for Earth in an earlier blog of mine. In short, the longer this minimum, the cooler the earth is going to be over the next decade or two. See my Mar23 blog. This is EASILY the deepest solar minimum since 1913. We've already easily exceeded the number of spotless days of all the intervening minimums, and you can see from the charts below that we should expect many more. The deepest minimum since 1913 was 568 spotless days in the 1933 solar cycle. This minimum has exceeded that with our current number of 594, and it is easy to imagine looking at the chart above that we will exceed the 1019 spotless days of the 1913 minimum. The graph immediately below charts spotless days in orange for the current minimum up until mid-May2008... About ten tall orange bars must be added to the upper graph below in order to bring it up to the present date, as can be seen from the graph I link at the bottom of this page. ![]() The lower chart shows the 1933 minimum spotless days. There really is no indication from these charts that we've clearly hit the midpoint of the spotless days of this cycle. If you mash the link below, you can see the period June 2007-Mar2009... to show that we need to add many orange bars to the graph above. It also shows in blue the 1996 solar minimum.

I'll put a link in the comments below when I do so. |
