[AZ-Observing] Solar Activity

Space Weather News for Sept. 10, 2005
http://spaceweather.com

Solar activity remains very high and shows no signs of abating. 
Sunspot 798/808 has unleashed seven X-class solar flares since Sept. 
7th. Forecasters say there's a 75% chance of more X-flares during the 
next 24 hours, possibly causing radio blackouts and radiation storms.

Coronal mass ejections hurled into space by these explosions could 
hit Earth's magnetic field in the days ahead.  Sky watchers, 
particularly in northern places like Canada and Alaska, should remain 
alert for auroras. The best time to look is  local midnight.

The sun's 27-day rotation is slowly turning sunspot 798  to face 
Earth. Explosions in the coming week will be increasingly 
Earth-directed, raising the possibility of geomagnetic storms and 
auroras over the continental United States, Europe and Australia.
