Geomagnetic Activity Alert -- possible aurora tonight
A gust of solar wind on February 24 at 1430 UT may have triggered an intense geomagnetic substorm recorded by NASA's Polar satellite. That event is subsiding, but the solar wind velocity is still high and variable.
Observers in Alaska, Canada, and the northern tier of US states should be on the lookout for active aurora tonight. More information and updates about the ongoing geomagnetic disturbance will be posted at SpaceWeather.com
Aurora and other geomagnetic events will be easier to predict when space physicists have a global view of Earth's magnetosphere and better space weather diagnostics. A new NASA mission to the magnetosphere, called IMAGE, is slated for launch on March 15, 2000.
