Uh oh. I see likely August blackouts in the crystal ball.
Growing sunspot could unleash a major solar storm

Bring on the Sonic Firestorm!

I thought we were in a solar minimum right now. weird

I hope that these solar storms will not effect any electronic equipment like Computers (Laptops/Desktops), PDAs, VCRs, and other appliances that rely on electronics if they are turned off.

So is this a "doomsday" event I should stock up food supplies and such for? Or is this a "small" crisis?

Yep, but also lats fall i remember reading something about sun's magnetic field reversal, last fall, it was flatened at sun equator.
So maybe the sun's magnetic field is somehow rearrenging.
The 11 year cycle IIRC has nothing to do with magnetic field reversal, i can dig up to confirm.

Just a day or two ago I witnessed a really active aurora... Perhaps these are related?
If the solar flares are timed right, we won't be able to watch the Republican convention! Aw shucks!

Will not change his avata
we haven't had this kind of activity sense the world's become as computer-dependent as it is now have we? this will be very interesting...

Oh man, I think I'm going to move to New Zealand. That way when it hits earth it would be nighttime there, and I would have half the earth to shield me. I would also duck and cover to ensure more safety.

My guess is that the outcome will be similar to Nike's "Y2K" commercial a few years back, but that's just being pessimistic.

Speaking of magnetic fields... The earth's is weakening as well, possibly as a prelude to a north-south flip. If we get one of these storms when the field is neutral or close to it, the FAA might have to shut down air traffic instead of just routing them away from the Arctic Circle.

In fact, yes. Aurora occur when too much solar particles hit the Earth's magnetic field ; some find their way through (mostly at the poles because of the way a magnetic field acts over a sphere), and booom ionize the atmosphere.

The weakening -- if coupled with a subsequently large influx of radiation in the form of protons streaming from the sun -- can also affect the chemistry of the atmosphere, said Charles Jackman of NASA's Goddard Space Flight Center.
That can lead to significant but temporary losses of atmospheric ozone, he said.

But i have also read another article ( cant find it now), which say, that even if earth magnetic field weaken and flaten on equator, the solar wind flux coupled with the weak earth field will create an induce magnetic field that will still protect us.
Maybe that's why we dont see life instinction during past magnetic reversal ( it happened several time).
I will find the article and post link later.
Not the one i am searching for but a very good one, super computer simulation include,

They've also learned what happens during a magnetic flip. Reversals take a few thousand years to complete, and during that time--contrary to popular belief--the magnetic field does not vanish. "It just gets more complicated," says Glatzmaier. Magnetic lines of force near Earth's surface become twisted and tangled, and magnetic poles pop up in unaccustomed places. A south magnetic pole might emerge over Africa, for instance, or a north pole over Tahiti. Weird. But it's still a planetary magnetic field, and it still protects us from space radiation and solar storms.

Excellent link Tassadar, thanks.
Sun's spot cycle and sun magnetic reversal are related ( so i was wrong in my first post).

February 15, 2001 -- You can't tell by looking, but scientists say the Sun has just undergone an important change. Our star's magnetic field has flipped.
The Sun's magnetic north pole, which was in the northern hemisphere just a few months ago, now points south. It's a topsy-turvy situation, but not an unexpected one.
"This always happens around the time of solar maximum," says David Hathaway, a solar physicist at the Marshall Space Flight Center. "The magnetic poles exchange places at the peak of the sunspot cycle. In fact, it's a good indication that Solar Max is really here."

But i am sure it wasnt completly reverse, it take time, last fall it was flatened on equator.

Another excellent site, National oceanic and atmospheric center, space weather on line.

And this one form europeen space agancy, they talk about last falls huge coronal mass ejection, they have very nice animated picture of those.

Edit:
The ESA site is wondefull, it have a lots of publish article, just use the search function, it is amazing, lots of information. Their SOHO sattelite do a great work in conjonction with NOAA.
