Leif Svalgaard at AGU on the Current Solar Cycle: ‘None of us alive have ever seen such a weak cycle’
WUWT’s resident solar expert Dr. Leif Svalgaard (and others) says ‘None of us alive have ever seen such a weak cycle’ and the panel he was on talk about the…
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…
The sun is about to have a flipping magnetic field reversal
We’ve been watching the progress on the WUWT solar reference page in this plot from Dr. Leif Svalgaard: Solar Polar Fields – Mt. Wilson and Wilcox Combined -1966 to Present…
Dr. Leif Svalgaard on the New Scientist solar max story
An article in the New Scientist says: But Dr. Leif Svalgaard, one of the worlds leading solar physicists and WUWT’s resident solar expert has this to say:
NOAA SWPC updates their solar cycle graphs – 3rd straight month of dropping sunspot numbers
Normally, I run this post around the end of the first week of the month, but this month there was a problem. NOAA’s Space Weather Prediction Center (SWPC) botched the…
The sun is still in a funk: sunspot numbers are dropping when they should be rising
The sunspot number for February from SIDC is down again, to 33.1 Here’s the source of that data: http://sidc.oma.be/DATA/monthssn.dat So far, cycle 24 is significantly lower in SSN number that…
Interesting presentations from the Nagoya Workshop on the Relationship between Solar Activity and Climate Changes
As the sun goes blank today, just 15 months from the expected Cycle 24 solar maximum, Dr. Leif Svalgaard writes in to advise me of the presentations made in the…
