Huge solar flare jams radio, satellite signals: NASA

[jimbo123]

A powerful solar eruption that has already disturbed radio communications in China could disrupt electrical power grids and satellites used on Earth in the next days, NASA said.

Geomagnetic storms usually last 24 to 48 hours, "but some may last for many days," read a separate statement from the US National Weather Service (NWS).

"Ground to air, ship to shore, shortwave broadcast and amateur radio are vulnerable to disruption during geomagnetic storms. Navigation systems like GPS can also be adversely affected," it said.

Earth dodges geomagnetic storm

A wave of charged plasma particles from a huge solar eruption has glanced off the Earth's northern pole, lighting up auroras and disrupting some radio communications, a NASA scientist said.

But the Earth appears to have escaped a widespread geomagnetic storm, with the effects confined to the northern latitudes, possibly reaching down into Norway and Canada.
