Heads up - literally! Strongest geomagnetic storm in many years. If you live in the higher latitudes, keep an eye out for auroras. My cousin in Montana just posted some brilliant pics of some up there.
At these levels, voltage disruptions are even possible. The strangest part is that this was totally unexpected - no associated flare or CME activity.

@CharityFeb yikes! Thanks for the heads up
@perpetualmystic The Rapid City mention is from a family member?
@mitch no, not a family member or anyone I knew.
