Big Coronal Mass Ejection Due today

The Sun burped day before yesterday and emitted a coronal mass ejection towards Earth when the magnetic field around a sunspot collapsed. The CME and the solar wind should combine today and cause a lot of aurorae at both poles and possibly into the northern tier of the lower 48. If your are going to be in the North country look for green skies tonight. A video of the ejection can be seen on nasa.sdo.gov or at spaceweather.com.
