GEOMAGNETIC ACTIVITY: Earth's magnetic field is reverberating from a CME impact during the early hours of Jan. 22nd. The hit compressed Earth's magnetic field, briefly exposing some geosynchronous satellites to solar wind plasma, and disturbed the ionization structure of Earth's upper atmosphere. As night falls on Jan. 22nd, Arctic sky watchers are reporting bright auroras in response to a polar geomagnetic storm (Kp=5). Please check http://spaceweather.com for images and updates.
STORM ALERTS: Would you like a call when geomagnetic storms are in progress? Storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
