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.
