SOUTHERN CORONAL HOLE
A vast hole has opened in the sun's atmosphere over the sun's south pole. The gap, also known as a coronal hole, is colored cobalt blue in this extreme UV image of the sun from NASA's Solar Dynamics Observatory.

Coronal holes are places where the sun's magnetic field spreads apart and allows solar wind to escape. Streaming along open lines of magnetic force, see the arrows above, hot gas flows outward at speeds exceeding a million mph. A stream of solar wind from this coronal hole is expected to reach Earth in the days ahead. NOAA forecasters estimate a 55% chance of polar geomagnetic storms when the solar wind arrives.
