The solar fireworks at the weekend were recorded by several satellites, including Nasa’s new Solar Dynamics Observatory which watched its shock wave rippling outwards.

Astronomers from all over the world witnessed the huge flare above a giant sunspot the size of the Earth, which they linked to an even larger eruption across the surface of Sun.

The explosion, called a coronal mass ejection, was aimed directly towards Earth, which then sent a “solar tsunami” racing 93 million miles across space.

Images from the SDO hint at a shock wave travelling from the flare into space, the New Scientist reported.
Experts said the wave of supercharged gas will likely reach the Earth on Tuesday, when it will buffet the natural magnetic shield protecting Earth.

It is likely to spark spectacular displays of the aurora or northern and southern lights.
"This eruption is directed right at us," said Leon Golub, of the Harvard-Smithsonian Center for Astrophysics (CfA).
"It's the first major Earth-directed eruption in quite some time."

Scientists have warned that a really big solar eruption could destroy satellites and wreck power and communications grids around the globe if it happened today.

Nasa recently warned that Britain could face widespread power blackouts and be left without critical communication signals for long periods of time, after the earth is hit by a once-in-a-generation “space storm”.
The Daily Telegraph disclosed in June that senior space agency scientists believed the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013.

It remains unclear, however, how much damage this latest eruption will cause the world’s communication tools.
Dr Lucie Green, of the Mullard Space Science Laboratory, Surrey, followed the flare-ups using Japan's orbiting Hinode telescope.

"What wonderful fireworks the Sun has been producing,” the UK solar expert said.
“This was a very rare event – not one, but two almost simultaneous eruptions from different locations on the sun were launched toward the Earth.

"These eruptions occur when immense magnetic structures in the solar atmosphere lose their stability and can no longer be held down by the Sun's huge gravitational pull. Just like a coiled spring suddenly being released, they erupt into space.”

She added: "It looks like the first eruption was so large that it changed the magnetic fields throughout half the Sun's visible atmosphere and provided the right conditions for the second eruption.
"Both eruptions could be Earth-directed but may be travelling at different speeds.

“This means we have a very good chance of seeing major and prolonged effects, such as the northern lights at low latitudes."

Watch for the Aurora Borealis tonight if you have clear skies!

It's Y2K all over again. :)

I hope the extent of damage is minimal. Just think if a few key satellites are damaged. Some won't have a cell phone for a while. Maybe go without TV. ...The horror.
As far as more serious concerns, I'm sure the military has contingency defenses in case the system comes crashing down. :eek:

It's gonna be interesting to see.

Sometime around 2013? More likely 2012. 2012?!:eek::eek::eek: We're all gonna die! We're all gonna die!:p

So that's how the world ends; a solar fart in our general direction.:(

Ain't gonna do you any good.... We Canucks are short on beer (it's been a hot summer) and if the power cuts out and what little beer we have left gets warm, we be coming down for yours! So hide your brews... and head for the hills....

Don't trust anyone who is polite, or apologizes for no good reason - they may be spy... and if you hear the word 'eh'... well, it's too late.... you've been infiltrated....

Biggest military in world can't stop 35 million desperate, thirsty, poutine eating, beer drinking, hockey playing.....

wait one ...... wait one...... hold on......

I've just been informed that Molson's has ramped up their production lines.... you're safe.... for now......
:D

lol we're so insignificant. Our tiny little planet's power and communications grids can be destroyed by the sun farting.

There was a really freak heavy thunder storm earlier, completely out of the blue*, went from sunny to storm in under 10 minutes, dunno if it's related, I thought it was quite strange, it's sunny now too.

(*It's been sunny/cloudy here everyday for weeks)
