A strong solar storm is battering the Earth now and could amplify the planet's northern lights displays.
The solar storm is cosmic fallout from a massive solar flare on Thursday (July 12) that included a powerful eruption on the sun, known as a coronal mass ejection. The eruption sent a wave of charged solar plasma toward Earth, which was expected to arrive sometime between 5 a.m. and 9 a.m. EDT (0900 and 1400 GMT), according to forecasts by NASA and the NOAA-run Space Weather Prediction Center.
Space Weather officials said the solar storm could trigger a level G2 geomagnetic storm on Earth, a moderate-level event that could spark auroras at latitudes as low as New York or Idaho, after 9 a.m. EDT. Most northern lights displays, which occur when charged solar particle interact with Earth's upper atmosphere, are confined to high-latitude regions around the polar regions by the planet's magnetic field.
This weekend's solar storm originated from one of the most powerful sun flares to occur this year. The flare registered as an X1.4-class sun storm, one of the strongest flares the sun can unleash. It marked the sixth X-class solar flare of 2012.
The solar storm erupted from the giant sunspot AR1520, or Active Region 1520, which is actually a group of sunspots that at its peak may have stretched across186,000 miles (300,000 kilometers) of the sun's surface, NASA scientists have said.
The Space Weather Prediction Center is keeping a close watch on AR1520, as well as several other active spots on the sun, for signs of more activity.
"All eyes are on the solar wind data to note the expected passage on Saturday of a Coronal Mass Ejection (CME) from Thursday's solar event," center officials wrote in an update late Friday (July 13).
The solar storm is not expected to pose a major risk to satellites and spacecraft in orbit, or power systems on Earth, officials have said.
The sun is currently in the middle of an active phase in its 11-year sunspot cycle. The current cycle is known as Solar Cycle 24 and expected to peak in 2013.

This information should be on the nightly new! Instead our so called news media is bitching that USA Olympic uniforms were made in China. Only people who buy ONLY American clothes should whine.
More Solar System News!
That is until some Solar System news event disrupts the media outlets. But then they won't be able to talk about it...
This one however is not expected to, so on with the whining.
Not sure about a solar storm (I trust these guys) but there's intense solar heat bombarding Montreal right now.
