Bz will go down a little I'm sure. It'll be inetersting to see how long this last. But for us in Holland / Belgium theres this front that will entriely cover our little nations the comming night =\

Rest of europe not much luck either. Have been having a short chat with a few wether riding to germany would be viable. Although clouds are expected there as well, in lesser ammounts then here... Maybe they have a clear spot now and then?

Anyway, good luck to all, and I wish all that DO see this a LOT of fun!

Although speed and density aren't as big as used to be in a storm, this is a big shock to the earth's magnetic field  Shocked This is my first time i saw bz up to -60 and bt up to 60  Tongue

Unluckily the weather seems to be aware of the storm from days before, 'cause just now on this moment the clouds are getting thicker here in Belgium... and they forecast some very bad weather tonight  Embarrassed

if we have a chance to view auroral activity, the sky is obscured with thos bloody clouds and id an impact is comming with clear weather, it comes to late or isn't strong enough. hopefully someday we have clear skys...

anymway, spaceweather says that the second CME is still underway and could produce some heavier storm. Bz is not much good now, it went north again Cheesy

to all who have clear skys, good luck with the auroras

Wow, I had 124 email alerts so far today, one said the KP was 9!  It always seems to happen when it is either daytime here, or cloudy at night.   Cry

 Hi,

Just finished observations here in southern Finland (61.2 N, 23.5 E). I was watching from around 20-24UTC. Within first hour, clouds and about a minute of some bit brighter activity 10-20 degrees from northern horizon and behind the clouds. Also few very very very faint tall rays, couple of them up to the zenith. After the first hour au became marginal to non existant. This was nothing but afterglow...Seen it before too many times and it is hardly ever anything to remember afterwards. No reason to accuse at the moon, the power just was not there.

Br,

We had a wonderful – albeit brief display – here in the Ottawa area at 9:30 pm Eastern on Wednesday evening.

I scooted north of the city to Pink Lake in Gatineau Park to escape the light pollution.  My daughter and I – as well as a park patrol officer-- were rewarded with a memorable display.  How I enjoy summertime aurora – I’ve posted two representative images to the STD Real Time Image Gallery.

Hopefully, observers in central and western North America are -- or will be -- in the field checking things out.

adh, I seen the same thing you did and at the same time . Smiley
Did you see the patches " blob " looking aurora, Wabe B. has a good picture of that
posted on STD Gallery.
Nice pics BTW...
I took a few pics but afterwards i realized i fogot to check my iso setting, it was on 100 iso  Embarrassed
anyway i can still see the beams and patches in my pics, just nothing spectacular.
Thing i found most interesting is the KP was only at 5 durring my observation, i normally need
a KP around 6.5 to 7.
The observation report from Barberton Ohio was mine.

Dave:
 
Thanks for the feedback on the images -- putting the city lights well to the south really helped things out.  I could see the faint arc low to the horizon as twilight was fading and it is always interesting when several observers report pretty much the same display.  Too bad about your camera settings.
 
Yes, visually I did see a few brief "blobs" or “patches” and one in particular at 0151 UTC.  But a check of my digicam image taken at that time suggests that it was the more intense bottom of a curtain "folded over."  I’m attaching a lower-res jpeg for illustrative purposes that really won’t do it justice…

This is, I think, different from Wade's great image that looks to me like a more distinct bit of activity.  His “patch” was also taken about four hours after our observations.  I’m also not sure what settings he used on his camera to capture his image.
 
That being said, I have seen the “blob” or “patch” before, many years ago back in Northwestern Ontario.  I also recall Dominic Cantin up in Québec City capturing a few interesting images of the patch a few years back (see: http://www.spacew.com/gallery/image001287.html for a good example).

While I’d like to think that things will persist into this evening, I am not too confident: velocity and density seem reasonable, but the Bz seems to have settled slightly northward.  The Kp is bouncing around though we need a decent “4” here in order to detect an arc low to the horizon.

Good luck this evening.

I posted my " goof " of an image to the STD Gallery here, ...
http://www.spacew.com/gallery/image004858.html
Mainly for the sake of the "blob" "patch" conversation Smiley
The blob or patch was visible naked eye, as were some faint rays
and a arch that formed about 25 degrees above the horizon.
The blob would faid and brighten slightly but none of the activity
would last more than a couple minutes at a time.
What really amazed me though was the fact that when i went home
i checked several online data sources and the KP had only reached 5
at the time i took my images, and that was from 9:35 to 10:10 EST
or 1:33 to 2:10 UTC.
I normally need a good KP of 6.5 to 7 from my latitude.

Dave:

Not bad for a "goof" image.  After all, as Santa says, ya take what you can get... especially if you usually need a Kp above 6.
