Coronal Hole Facing Earth

A significantly large coronal hole rotated across the middle of the Sun to be in a position to affect Earth (Dec. 9 - 13, 2013). Viewed in extreme ultraviolet light, the dark region is where the magnetic field of the Sun is more open, emitting streams of high-speed solar wind. Over the next few days, this solar wind is likely to impact Earth's magnetosphere and possibly cause displays of aurora.

Oh, I hope there are lovely displays of the Aurora Borealis this year. When is it that the sun's polarity is supposed to shift?

Any time now.

It's not something that can be predicted with 100% accuracy. Astronomers have been expecting it since August.

Thank you for the link, Toast. I bookmarked it. I don't know much about space, physics or science, but it is a fascinating subject.

One thing I have never seen in the sky is the Aurora Borealis and have always wished I had.
