GEOMAGNETIC STORM: A stream of solar wind hit Earth's magnetic field on
Sept. 11th, sparking one of the strongest geomagnetic storms of the year
and auroras in multiple US states. This continues a trend of relatively
high geomagnetic activity that began on Sept. 7th. High-latitude sky
watchers could see more auroras tonight. Visit http://spaceweather.com for more information and updates.
