FYI: G3 Class Geomagnetic Storm in Progress

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.

1. No aurora here -- western rural MI

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.

...that would be a: ''It's possible.''



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.)**.

Lots of fade in from other stations and high pitched whining. Oh wait could be a hearing aide.....

weather, graphs, numbers, color and four of my favorite letters NOAA. Big kick. Thank you.

...this is only a G-3 level storm. Because any higher and we probably wouldn't be seeing much on our computers after the geomagnetic storm wiped out a few satellites!
