Will the next cycle be a Dalton Minimum repeat, or a start of a new Maunder Minimum?
This is what David Archibald went on to say to SC25.Com in a recent email...he believes that start of Solar Cycle 24 could also be the start of a new Dalton or Maunder Minimum, the historic cooler conditions on Earth (see the period on display on the above overlay) that correlate to low solar activity and "Global Cooling".
He then said that the Maximum Sunspot count he expects is HALF of that forecast by NASA, in that David only expects no more then 45 Sunspots at the SC24 Maxima (last seen in 1803), and in his own words "it could even be south of that".

David also pointed out....."Solar Cycle 24 might not start until some time in 2010, and then be 15 years long. So Solar Cycle 25 might not start until 2025"......so is it bad news for the site name, no,.......we will keep you informed on the progress of Solar Cycle 24...if that Solar Cycle is bad news then SC25 could be a lot worse.....stay turned.
