| Geomagnetic storm alert as solar wind and coronal mass ejection head for Earth |
Courtesy of Spaceweather.com A solar wind stream is heading for Earth, and so is a coronal mass ejection (CME). Together, they add up to a geomagnetic storm alert for March 17th and 18th. The impact of the solar wind plus CME will brighten Arctic skies already alive with Northern Lights. Tromsø northern lights picture gallery "We are getting some good activity here in Tromsø, Norway," reports Thomas Hagen. He took the picture on March 16th using a Canon 40D set at ISO 800 for 5 seconds. High-latitude sky watchers should take note of those camera settings. NOAA forecasters estimate a 30 percent chance of geomagnetic activity and a 5 percent chance of severe geomagnetic storms during the next 24 hours. Photo-ops are in the offing! Go back...  |
