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.
