Like 'the pause' in surface temperatures, 'the slump' in solar activity continues

The NOAA Space Weather Prediction Center has updated their monthly graph set and it is becoming even more clear that we are past solar max, and that solar max has been a dud. “The slump” continues not only in sunspot activity, but also other metrics. And, tellingly, Dr. David Hathaway has now aligned his once…

Solar Cycle 24 Update

Guest essay by David Archibald Recently, a number of newspaper articles spoke of the potential of cycle 25 to be   “Weakest Solar Cycle In Almost 200 Years”. “We’re in a new age of solar physics,” said David Hathaway of NASA’s Marshall Space Flight Center in Huntsville, Alabama. Here is a collection of solar measurements that…

Solar Cycle 24 Length and Its Consequences

Guest post by David Archibald Solar Cycle 24 is now three years old and predictions of the date of solar maximum have settled upon mid-2013. For example, Jan Janssens has produced this graph predicting the month of maximum in mid-2013, which is 54 months after the Solar Cycle 23/24 minimum in December 2008: For those…

Solar Max – So Soon?

Guest post by David Archibald Dr Svalgaard has an interesting annotation on his chart of solar parameters – “Welcome to solar max”: Graphic source:  http://www.leif.org/research/TSI-SORCE-2008-now.png Could it be?  It seems that Solar Cycle 24 had only just begun, with solar minimum only two and a half years ago in December 2008. The first place to…

NASA's Sunspot Prediction Roller Coaster

Guest Posting by Ira Glickstein Santa brought us a new Sunspot prediction to be added to NASA’s incredibly high series of at least five ill-fated predictions starting in 2006. NASA’s latest peak Sunspot Number for Solar Cycle #24 (SC24) is down 60% from their original, but it still seems a bit too high, judging by…
