Solar coronal mass ejection this week causes aurora borealis in the South; a precursor to a "Carrington Event"?

The site “Space Weather” has many pictures from many states of the spectacular aurora borealis displays that occurred as far south as northern Mississippi Tuesday Oct. 24.  The link is here

A coronal mass ejection strong enough to produce such strong colors this far south probably could have run the risk of disrupting not only satellites but even power grids on the surface, as with Quebec in 1989, or maybe the 19th Century Carrington Event.  This does not seem to have happened.

Solar flare activity seems to be increasing, and power grids ought to be looking at ways to harden themselves
In the DC area, there was too much light pollution for me to see it.
