*GEOMAGNETIC STORMS PREDICTED (G2-CLASS):* A large hole has opened in 
the sun's atmosphere, and it is spewing a stream of solar wind toward 
Earth. Estimated time of arrival: Oct. 24th. First contact with the 
gaseous material is expected to produce minor G1-class geomagnetic 
storms, intensifying to moderately strong G2-class storms on Oct. 25th 
as Earth moves deeper into the stream. Arctic sky watchers can expect to 
witness bright auroras. The lights could descend to lower latitudes as 
well, with sightings in northern-tier US states along a line from Maine 
to Washington. Visit Spaceweather.com
