GEOMAGNETIC STORMS: Last night, Earth passed through a region of
south-pointing magnetism in the solar wind. This triggered a G2-class
(Kp=6) geomagnetic storm. At its peak, the storm spawned Northern Lights
in the USA as far south as Kansas. More auroras are in the offing as a
CME is set to deliver a glancing blow to Earth's magnetic field on June 8-9. Check http://spaceweather.com for photos and updates.
