GEOMAGNETIC STORM PREDICTED: On Nov. 6th, Earth will cross through a fold in the "heliospheric current sheet"--a vast system of electrical currents that ripples through interplanetary space. A day later, on Nov. 7th, a fast-moving stream of solar wind is expected to engulf our planet. The combined effect of these two events could spark polar geomagnetic storms. NOAA forecasters say there is a chance of G1-class storms on both Nov. 7th and Nov. 8th. Arctic sky watchers will likely see auroras mixed with moonlight on those dates, while photographers in northern-tier US states may be able to capture the lights using digital cameras with nighttime ISO settings.
