Space Weather News for August 24, 2003

AURORA SEASON: In less than one month Northern autumn will begin--and that
means aurora season is beginning, too. Geomagnetic storms tend to be most
intense during the weeks around the September equinox because the
interplanetary magnetic field (IMF) near Earth tips farther south than
usual at that time of year. South-pointing IMFs encourage auroras.
September and October are usually best, but already in August sky watchers
from Canada to Arizona have been enjoying colorful Northern Lights. Visit
