STORM IN THE OFFING: A canyon-shaped hole has opened in the sun's
atmosphere, and it is spewing a stream of high-speed solar wind toward
Earth. NOAA forecasters say there is a 30% chance of polar geomagnetic
storms (G1-class) when the gaseous material reaches our planet on
August 31st. High-latitude sky watchers should be alert for auroras
this Thursday and Friday.
