COMES THE SOLAR WIND: The Arctic Circle is about to turn green.
Forecasters say there is a good chance of bright auroras around the
poles on Sept. 20th when a solar wind stream engulfs Earth's magnetic
field. Researchers have long known that auroras favor equinoxes. The
timing of the stream could scarcely be better as it is expected to
arrive only two days before the beginning of northern autumn.
