"More lights are possible on Jan. 23th when a negative-polarity solar wind stream is expected to hit Earth's magnetic field. NOAA forecasters estimate a 20% chance of polar geomagnetic storms when the stream arrives."
Talking about lights, taking the dog down the track in a blizzard this evening, massive lightening flash gave me a bit of a fright. The rumble was a few seconds later though. Bit of a surprise nonetheless.
