Just heard that several new major eruptions have been again reported on the Sun. If you missed the last burst, try for this one.

mm, I think it takes a few days from eruption, depends on exact timing and position of earth

no serious...
i don't know anything about the sun other than it's hot when we see it
and it's cold when we don't..
why are getting all these bursts? wut would happen if it keeps on coming?

well its been there 4 billion, should be good for another 4, but hey, it could always flare, some scientists think that happens every few hundred million years or so......

That's the one I use! Right to pmap just like that. From the noaa site you can get to the space weather page and see their 3 day predictions!
I will have good weather Thursday and that's a projected "good day".
Peace, Stever

See:
http://sec.noaa.gov/advisories/bulletins.html
for the info about this latest solar blast.
It's also discussed on http://www.spaceweather.com
In a nutshell, this was an immense flare, perhaps the largest since this sort of measurement was taken (1976-ish). It was from the same complex of sunspots that caused the three x-flares last week, but it has now moved (the sun rotates about once every 27 days or so) to the limb - that is, the edge as it rotates around. This means that the CME was not pointed directly at Earth.
However, this thing was so big that even with a glancing blow it could spark aurora to mid-latitudes. As of now (8:25 PM) the experts don't know exactly when because they need to take precise measurements of the velocity of the Earth-directed portion.
They should have a good grasp of the projected impact time by tomorrow morning. This flare and CME is likely moving fast, so don't expect it to take several days.
BTW, the people at http://www.spacew.com have nailed the timing of the impact of these recent events on Earth to within a couple of hours. They've been more accurate than the SEC people. The best way to keep up with the timing is to go to spacew.com and open the discussion forum.

Scroll and look for posts from Cary Oler. This guy is the main operator of this site and he's good. Real good.
Good luck to all - we'll probably be snowed out in Denver

Hey, you never know, it could be! But just think of all the great pics you'll get.....Awesome Aurora's, second coming of the Ice Age, you get to practice your low-light photography until you become a seasoned professional. I just don't see any down side to this........Oh yeah, total darkness, -250 degrees fahrenheit and death to all living beings warm blooded and cold....Yeah, that would kind of suck, scratch that idea.

So this blast will take a day or two to reach earth (to become aurora) ?
I hope I can spot it here in AZ.

See:

Basically, it should impact tonight for N. America - the projected time + - a few hours is 2 AM EST (or 11 PM on the west coast). The uncertainty is more + than -, meaning that if this time is off, it's more likely to be later than earlier.
But note that the magnetic field at the time of impact is supposed to be northward. This doesn't bode well for aurora (the magnetic field is akin to a door - if it's northward it's closed, southward it's open -- very flimsy analogy, but reasonably accurate). Howver, the Bz component of the magnetic field can swing southward in just a matter of minutes.
So what does this mean? Once impact occurs - and spacew's discussion forum is a great place to keep tabs on this - it's a game of chance. You might have to wait a few hours for the magnetic field to swing southward. It might not happen. It might happen for only a short time. A lot of things have to happen in order to have mid-latitude auroras. Numero Uno on this "things" list is to have the sun behave properly. And it's doing that.
As far as Arizona, based on what I'm reading it's not a big chance. The projected force of this is considerably smaller than the big ones last week (which were seen as far south as Orlando!). But if I was living in AZ and the skies were clear I'd give it a try. You can always get by with a lousy night's sleep, but you don't have many chances - even if slim - to see aurora. So find that nice, dark, clear sky and give it w whirl.
But that's just me.
