Strong to Extreme Space Weather Warning issued from CME

A solar space weather storm is in progress. This weekends CME has caused NOAA to issue a Strong to extreme storm warning. This could cause electrical issues and problems with satellites. Could make for some good viewing of Auroras though. See below for details.

ALERT: Geomagnetic K-index of 7
Threshold Reached: 2012 Oct 01 0300 UTC
Synoptic Period: 0000-0300 UTC

Active Warning: Yes
NOAA Scale: G3 – Strong

Potential Impacts: Area of impact primarily poleward of 50 degrees Geomagnetic Latitude.
Induced Currents – Power system voltage irregularities possible, false alarms may be triggered on some protection devices.
Spacecraft – Systems may experience surface charging; increased drag on low Earth-orbit satellites and orientation problems may occur.
Navigation – Intermittent satellite navigation (GPS) problems, including loss-of-lock and increased range error may occur.
Radio – HF (high frequency) radio may be intermittent.
Aurora – Aurora may be seen as low as Pennsylvania to Iowa to Oregon.

Issue Time: 2012 Oct 01 0243 UTC
