�Personally, I�m betting that sunspots are coming back,� says researcher Matt Penn of the National Solar Observatory (NSO) in Tucson, Arizona. But, he allows, �there is some evidence that they won�t.�
Penn�s colleague Bill Livingston of the NSO has been measuring the magnetic fields of sunspots for the past 17 years, and he has found a remarkable trend. Sunspot magnetism is on the decline.
I had
blogged about it on August 21st.
The thing to look at is this -- the magnetic strength of the sunspots:
Last winter was brutal, this coming winter should be interesting...
