Earth's polar magnetic field is storming as our planet passes through a
region of south-pointing magnetism in the solar wind. Last night (Aug. 26-27),
observers around the Arctic Circle saw some of their first auroras in
months and Northern Lights descended across the Canadian border into
multiple US states. Solar wind conditions favor more geomagnetic storms
and high-latitude auroras on Aug. 27-28. Check http://spaceweather.com for more information and updates.
