Powerful Solar Explosion to Trigger Strong Geomagnetic Activity
5 Nov 2001
A powerful solar explosion on Nov. 4th sparked an X-class solar flare and hurled a bright coronal mass ejection toward Earth. The expanding cloud will probably trigger strong geomagnetic activity when it sweeps past our planet on Nov. 6th or 7th. Sky watchers, even those living at middle latitudes, should be alert for auroras during the nights ahead.
