Chance of aurora borealis - from Cliff Mass:
Potential Aurora Tonight!
One of the most extraordinary natural sights to behold is the aurora borealis and tonight and early Sunday morning, you might have a chance to see one in our region.
On Wednesday, there was a massive solar flare, followed by a coronal mass ejection (CME), on the sun. It takes a few days for electrons and protons associated with the CME to reach the earth's atmosphere, and in fact, it has JUST ARRIVED. This is evident from the latest planetary K index (a measure of the disturbance of Earth's magnetic field) form the NOAA Space Weather Prediction Center.
Forecast is for partly cloudy so we will see...
