After an unusual hiatus sun spots are back.
There are some posts on Dredd Blog that explain why sun spot activity is a national security issue.
Also discussed is why it is an issue in the greening of the power grid which will be done by upgrading it to accept wind and solar generated electricity.
During the upgrade the power grid needs to be made more safe from other events associated with Sun Spots, or catastrophic results may develop.
The good news is that the Sun has not gone strange on us into some mode we do not understand with our current scientific model of the Sun.
