Solar Eruption may result in Northern Lights (North Pole) ... Satellite Disruption not ruled out

The Earth could be hit by a "solar tsunami" anytime now as an unusually complex magnetic eruption on the Sun has flung a large cloud of electrically charged particles towards our planet, scientists have warned.

Several satellites, including Nasa's new Solar Dynamics Observatory (SDO), recorded on Sunday a small solar flare erupting above sunspot 1092, the size of the Earth.

The satellites also recorded a large filament of cool gas stretching across the Sun's northern hemisphere also exploded into space.

The explosion, called a coronal mass ejection, was aimed directly towards Earth, which then sent a "solar tsunami" racing 93 million miles across space, the New Scientist reported.

When the violent cloud hits, which could be anytime now, it could spark aurorae in the skies around the poles and pose a threat to satellites, although not a severe one, it said.

Despite being separated by hundreds of thousands of kilometres, the two events may be linked, said astronomers who studied the images from SDO that hint at a shock wave travelling from the flare into the filament.

"These are two distinct phenomena but they are obviously related," said Len Culhane, a solar physicist at the Mullard Space Science Laboratory, University College London.

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 Centre for Astrophysics.

"It's the first major Earth-directed eruption in quite some time," Golub was quoted as saying by the Telegraph.

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".
