Last edited Mon Oct 1, 2012, 12:20 PM - Edit history (1)
Space Weather Message Code: ALTK06
Serial Number: 294
Issue Time: 2012 Oct 01 0443 UTC
ALERT: Geomagnetic K-index of 6
Threshold Reached: 2012 Oct 01 0439 UTC
Synoptic Period: 0300-0600 UTC
Active Warning: Yes
NOAA Scale: G2 - Moderate
Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.
Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.

(40,416 posts)Just checked. Semi-dark skies here. National forest area. Nearest town, 15 miles.
I have nice northern horizon. Could be a glow there, but no apparent aurora.
...maybe next time!

G 3 - Strong
Power systems: voltage corrections may be required, false alarms triggered on some protection devices.
Spacecraft operations: surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems.
Other systems: intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.)**.

(19,288 posts)Lots of fade in from other stations and high pitched whining. Oh wait could be a hearing aide.....

(22,656 posts)weather, graphs, numbers, color and four of my favorite letters NOAA. Big kick. Thank you.
