Apparently, auroral activity was seen as far south as the Dakotas in the hours before sunrise today.
The storm is subsiding but still active, so a chance to see some may be possible after dark in the northern tier of the U.S.
As an aside, the only time signal I can hear at the moment is WWV's 5 MHz signal.
