Space Weather News for August 17, 2006
http://spaceweather.com AURORA WATCH: An explosion on the sun yesterday (Aug. 16) hurled a coronal mass ejection (CME) toward Earth. The approaching cloud could spark a geomagnetic storm when it arrives, probably on August 18th. Sky watchers should be alert for auroras. If a storm erupts, the best displays will be at higher latitudes: e.g., Alaska, Canada, and Scandinavia. However, auroras could descend to lower latitudes, too, spreading across northern-tier US states from Maine to Washington and elsewhere. Sometimes during a geomagnetic storm, the sky appears to be blank--no auroras. The display may be too faint to see with the unaided eye. Try using your camera: a 15+ second exposure can reveal colorful auroras just below the threshold of naked-eye visibility. An example of "photographic auroras" over Colorado may be found in our most recent aurora gallery: http://www.spaceweather.com/aurora/gallery_01aug06.htm Please visit http://spaceweather.com for pictures of the August 16th explosion and updates about the incoming CME. |

Other than movies,magazines,I never have seen an Aurora Borealis in
person before.I guess I would like to,but they would have to drape their curtains over Mississippi for me to see them,and that is not likely to ever happen. cuhulin |
