Sunspot slide - we had a legitimate solar weather warning overnight at work last night. Predictions of strong geothermal magnetic disturbances, with 3 peaks of K7 on our scale.
They can affect the power grid, but overnight, there were no detrimental effects. Other than the absolute PITA of reporting and coordinating the information flow with the rest of the power entities.
There are several dashboards on the space weather prediction center. In my line of work, the electric power community dashboard is the site of choice...

Re Sunspot:
Interesting. How long does the average disturbance last?
Seger grew up around the Ann Arbor area, about 45 minutes (AKA, 2 beers) from my hometown.
As a sneaky teenager, I saw some of his early, local bar stuff.
