Mynaeris,

Pretty much what the article says.
Sometimes powergrids have problems, there could be some
power outages. Nowadays, with the amount of warning we get,
Most satellites can be put into a "safe" mode. Which minimizes the
chances of damage (not always though).

It's worse, when there is a one-two punch.
The Earths magnetic field doesn't get to recover, and more particles can make
it to the atmosphere. Thus the chances are greater for power outages etc..

If you've never seen the Aurora Borealis, this increases the chance.
I have some photos from last year, when we were pummeled one after another, by some pretty big CME's..Mayeb I'll post a good one later?

Can I ask you for a link for where you got this article?

Well, if you look at the Spaceweather site, you'll see that the storm is already fading. It doesn't look as though the KP index went totally off the charts, there.

SEC has updated with this warning....what the heck does it mean?

July 27 2058 UTC EXTENDED WARNING: Proton 10MeV Integral Flux above 10pfu expected

I predict no major disasters within the next few days. Just relax, it's just a little storm. A hundred years ago no one would have even known if we were having a massive geomagnetic storm unless there were lights in the sky. Hmmm, lights in the sky, that might be something to watch for and get excited about. It would be nice if I could see that.

Our dependance on electonics is much greater now than it was 100 years ago

Anyone know what the readings were on that extremely strong storm that happened last november?

Solar Activity being related to earthquakes, I've never heard such a crazy idea in my life.

I think that one was off the charts of the instruments that were observing them from SOHO. It was like a class X25-30 i think?

Hmm. Learn something new around here every day, I do.

Solar flares tend to be subjects of extreme fear in many circles. I'd like to track this one (what its strength is and so forth) and perhaps get some good links explaining evertying... and let's document its effects.

And the next time someone shrieks "OMG!!! SOLAR FLARE WILL TURN EARTH TO TOAST!!!" we can point them to this thread and say, "have a look at the benchmarks, eh?"
