Look out lovelies this is going to be a doozy when it reaches us on the December 5-6th!
VAST HOLE OPENS IN SUN’S ATMOSPHERE: A vast hole in the sun’s atmosphere–a “coronal hole”–has opened up in the sun’s northern hemisphere, and it is spewing a broad stream of solar wind into space. NASA’s Solar Dynamics Observatory photographed the coronal hole during the early hours of Dec. 3rd. (Photo below)
Coronal holes are places where the sun’s magnetic field opens up and allows solar wind to escape. Hot plasma flows outward at speeds exceeding a million mph. In the extreme-ultraviolet image, above, the boundaries of the coronal hole are traced by dashed lines; arrows indicate the escape of hot plasma.
Solar wind flowing from this coronal hole will reach Earth beginning ~Dec. 6th, and our solar wind environment will be dominated the stream for days after first contact. High-latitude sky watchers should be alert for auroras. (NASA)
GROUND, GROUND, GROUND YOURSELF- I cannot stress it enough through high solar activity!
