The American Astronomical Society is meeting a Mexico State University in Las Cruces, NM, and promised a big announcement today and here it is:
“If we are right, this could be the last solar maximum we’ll see for a few decades,” Hill said. “That would affect everything from space exploration to Earth’s climate.”

- Some unusual solar readings, including fading sunspots and weakening magnetic activity near the poles, could be indications that our sun is preparing to be less active in the coming years.
- The results of three separate studies seem to show that even as the current sunspot cycle swells toward the solar maximum, the sun could be heading into a more-dormant period, with activity during the next 11-year sunspot cycle greatly reduced or even eliminated.
In the past a less active sun has resulted in a cooler earth and during the Maunder Minimum, it brought on a mini-iceage. Here are some links to information on the Maunder Minimum at The Dalton Minimum Returns:
Maunder Minimum 1740—replay in 2020? (Updated)
Synchronized Northern Hemisphere climate change and solar magnetic cycles during the Maunder Minimum
Chilling Evidence: No Spots by 2015
There will be more information and discussion at Watts Up With That. I will be writing more on the long term implications of a return of a Grand Minimum.
