Biggest Solar Storm In Years Races Toward Earth

Gee...didn't we just experience something similar to this a few weeks ago?  Subatomic particles have already hit the Earth and have caused radio and radiation disturbances.  Gosh!  Disruptions?  It clearly sounds like an assortment of events could take place today and I'm serious about that. (That's what the article says)  You must admit that what happens in the upper atmosphere is quite interesting and there's certainly alot going on up that way today.  I'll be watching and as long as the activity doesn't disturb my internet service to my already faultering computer or knock out my cooking stove I should be okay.

The article below is very interesting.

WASHINGTON (AP) - The largest solar storm in five years was due to arrive on Earth early Thursday, promising to shake the globe's magnetic field while expanding the Northern Lights.

The storm started with a massive solar flare earlier in the week and grew as it raced outward from the sun, expanding like a giant soap bubble, scientists said. When it strikes, the particles will be moving at 4 million mph.

"It's hitting us right in the nose," said Joe Kunches, a scientist for the National Oceanic and Atmospheric Administration in Boulder, Colo.

The massive cloud of charged particles could disrupt utility grids, airline flights, satellite networks and GPS services, especially in northern areas. But the same blast could also paint colorful auroras farther from the poles than normal.

Astronomers say the sun has been relatively quiet for some time. And this storm, while strong, may seem fiercer because Earth has been lulled by several years of weak solar activity.

The storm is part of the sun's normal 11-year cycle, which is supposed to reach peak storminess next year. Solar storms don't harm people, but they do disrupt technology. And during the last peak around 2002, experts learned that GPS was vulnerable to solar outbursts.

Because new technology has flourished since then, scientists could discover that some new systems are also at risk, said Jeffrey Hughes, director of the Center for Integrated Space Weather Modeling at Boston University.

A decade ago, this type of solar storm happened a couple of times a year, Hughes said.

"This is a good-size event, but not the extreme type," said Bill Murtagh, program coordinator for the federal government's Space Weather Prediction Center.

The sun erupted Tuesday evening, and the most noticeable effects should arrive here between 1 a.m. and 5 a.m. EST Thursday, according to forecasters at the space weather center. The effects could linger through Friday morning.
