Space Weather News for Oct. 24, 2011

CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field on Oct. 24th around 1800 UT (2 pm EDT). The impact strongly compressed our planet's magnetosphere and may have exposed geosynchronous satellites to solar wind plasma. Mild to moderate geomagnetic storms are possible in the hours ahead as Earth's magnetic field continues to reverberate from the hit. Sky watchers in Scandinavia, Canada, and northern-tier US States should be alert for auroras, especially during the hours around local midnight. Check http://spaceweather.com for updates.

If you haven't backed up your data.... now's a good time. :)

The 10 day forecast in Texas is fairly steady except for a little cool front bringing in a slight possibility for rain (yeehaw!) on Thursday.

The 10 day forecast in Texas...

All y'all got a lot of "space" down there in the Great State Of Texas, but not that much. :)

I’ll go out and take a gander at the northern sky tonight. Clear skies here in Michigan tonight.

At least it doesn’t seem to be a Carrington event — as evidenced by the fact that FR is still up and running!

Update #1: Analysts at the Goddard Space Weather Lab say the CME impact caused a strong compression of Earth's magnetic field, allowing the solar wind to penetrate all the way down to geosyncronous orbit for a brief period between 19:06 UT and 19:11 UT. Earth-orbiting spacecraft could have been directly exposed to solar wind plasma during that time.

Update #2: Strong ground currents have been detected in Norway.

I’ve lived at the 45th parallel my entire life and never seen an aurora. Of course >320 days of cloud per year doesn’t give us many chances.

Same here in upper Il. Only seen the Northern Lights once from here but they were beautiful.

I wondered what hit me around 2 pm. I felt like I was run over by a truck!

I think it was about 20 years ago there was a spectacular display seen as far south as Texas. I remember because it was so bright out like a full moon but red.

So THAT’S why Excel has been crashing all day!

[CrazyIvan]

About 8 years ago here. Looked like scarlet curtains.

Thanks KoRn.
