A big dark hole in the sun's atmosphere, a 'coronal hole', is
turning toward Earth spewing solar wind. According to NASA's
official rubber chicken, it looks an awful lot like a bird:
Coronal holes are places where the sun's magnetic field opens up
and allows the solar wind to escape. A chicken-shaped stream of
solar wind flowing from this coronal hole will reach Earth on
June 5th - 7th, possibly stirring geomagnetic storms. High-
latitude sky watchers should be alert for auroras. Comments
