Source - Space Weather News for June 17, 2012: http://spaceweather.com
As predicted, a double CME hit Earth's magnetic field on June 16th. The
impact strongly compressed Earth's magnetosphere, exposing
geosynchronous satellites to solar wind plasma and sparking more than 24
hours of geomagnetic storms. (The storms are still in progress as this
alert is being written during the middle hours of June 17th.) In the
United States, Northern Lights have descended as far south as Wisconsin,
Washington, Minnesota, and the Dakotas. Southern hemisphere observers
are also reporting colorful aurora australis. Check http://spaceweather.com for photos and updates.
AURORA ALERTS: Would you like a call when geomagnetic storms are underway? Aurora alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
