News to me...

It doesn't seem to be a great cause of concern, but I think the subject will lead to mass reading of the NASA website. All in all, a good thing.

I mean, who knew the sun has a relatively predictable 11-year cycle of 'behavior'?

Feel free to bring related articles and primers for sun n00bs.

The eleven year "sunspot" cycle had been known for quite a while. It will be an important consideration if we send people to Mars.

Anyone who was in the same geography class as me, aged 13, in 1965.
