RETURN OF A BIG CORONAL HOLE:  At the end of October, a hole in the 
sun's atmosphere lashed Earth's magnetic field with solar wind, sparking 
moderately-strong geomagnetic storms and almost a full week of Arctic 
auroras.  News flash:  It's back. The same "coronal hole" is turning 
toward Earth again. Forecasters expect the solar wind to reach Earth 
during the late hours of Nov. 22nd with minor G1-class geomagnetic 
storms possible on Nov. 23rd. Visit Spaceweather.com for more
