Along with the still-rising S3 proton storm, the forecast for the incoming CME hit the Kp breakdown:

Nice and chilly out there, so I probably won't try to prop up the 6m antenna tonight. Will be interesting to see if there's city-visible aurora here in Madison, though!

There was a X1.9 solar flare on Sunday with a full halo CME.  The Space Weather Prediction Center has a 

G4 (Severe) Geomagnetic Storm Watch with the CME arriving as early as late January 19th (EST) to early January 20th.
