The Aurora Show is ON

The SUN

IMPACT: The coronal mass ejection described below has reached Earth (at approximately 0630 UT on Oct. 29th) and apparently triggered a strong geomagnetic storm. Red auroras have been spotted as far south as central California. Stay tuned for updates.

Maybe the best auroras of our lives tonight.

Instruments just beginning to show arrival of CME. Already a fine show in Seattle. Should intensify as night goes on.

[Siegfried]

It is indeed the best I've ever seen in my life. Here in north central Oregon we've got bright blue-green all around the northern horizon with pink and rose extending further, almost to the zenith.

Any particular direction in the sky?

[bonfire]

watching here in Dallas. Gorgeous!

Look north and above. Be patient. They come and go.

What fine show in Seattle? All I see are clouds. >:-(

[Hunble]

Are you sure those are clouds? Here in Minnesota, the aurora was so bright that I thought was a cloud.

Then I kept watching it....

[Steve_Stifler]

Cloudy skies here, but clear skies expected Wednesday night. Will the show still be going on then?

[Iconoclast2]

Nothing visible 30 miles south of Portland, Oregon.

The auroral oval can oscillate N and S hundreds of miles in a few minutes. instrument plots show the aurora should have been easily visible in Oregon (given clear skies) off and on for the past hour or so.

Activity may continue to intensify the next few hours.

[John H K]

It's quite possible, apparently, but I wouldn't count on it.

[Don W]

I can't see anything but stars in Victoria BC

[ALASKA]

Here at Auroral Ground Zero, we had a sky full. Dancing greens and rare reds. Incredible show for a while. I can hardly wait for tomorrow.

South of the city it's clearer.

[Rams82]

Give me some of what you guys are taking i see nothing!

Was just out and it's quiet at the moment. A while ago, all to the north was a green haze. Then red lines extended across the zenith. they come and go.

Kp index now pegged at 9!

Comment added at 09:32 UTC: The planetary A index for the 06-09h UTC interval reached the maximum possible value, 400 (Kp 9). Please note that solar wind data from both ACE and SOHO is currently near useless. SOHO is either experiencing sensor problems or has had some kind of failure due to the combined destructive potential of the intense radiation storm and the extreme solar storm.
