Large Coronal Hole has Formed in the Sun's Atmosphere
A large hole in the sun's atmosphere has formed and it is turning toward Earth.
This is a "coronal hole"--a region where the sun's magnetic field has opened up, allowing solar wind to escape.
A stream of solar wind emerging from this coronal hole could reach Earth as early as Dec. 7th and influence the near-space environment of our planet for several days.
G1-class geomagnetic storms and high-latitude auroras are possible when the solar wind arrives.
The forecast will improve in the days ahead as the hole rotates into better view, revealing its form and dimensions.
