Potential Impacts: Area of impact primarily poleward of 45 degrees Geomagnetic Latitude.
Induced Currents - Possible widespread voltage control problems and some protective systems may mistakenly trip out key assets from the power grid. Induced pipeline currents intensify.
Spacecraft - Systems may experience surface charging; increased drag on low earth orbit satellites, and tracking and orientation problems may occur.
Navigation - Satellite navigation (GPS) degraded or inoperable for hours.
Radio - HF (high frequency) radio propagation sporadic or blacked out.
Aurora - Aurora may be seen as low as Alabama and northern California.

Just uploaded a video showing the previous week's solar activity - as seen from LASCO C3/C2 + SDO.

If you slow / pause around the 15th (half-way) you can see the CME which caused today's events erupt...too big to miss.

Remember the Ariana Grande Music Video that showed a electric storm?

Aurora as far south as Alabama?

Thanks for info...was looking around ta see if something was going on...ringin in ears and my upper left shoulder killing me.

I only get like this with a high mag storm.as far south as Alabama?

That would be me them and already im showing signs of this latest blast...today gonna sux.

My stomach has been hurting me today but I doubt it's related to the solar storm

There has been a really intense display of Northern lights in Iceland recently.
This time they are unusually colorful, green, red, pink and violet.
