GEOMAGNETIC STORM WATCH: NOAA forecasters say there is an 80% chance of
polar geomagnetic storms on Aug. 4th when a solar wind stream is
expected to buffet Earth's magnetic field. The wind is flowing from a
canyon-shaped hole in the sun's atmosphere, so wide that it is almost
bisecting the solar disk. Storm levels could reach G2-category
(moderately strong) during the late hours of Aug. 4th, subsiding to
G1-category (minor) on Aug. 5th. Visit Spaceweather.com for more
