Solar Flare Erupts, Creating Great Display

GREENBELT, Md. – A medium-sized solar flare has erupted from the sun in an impressive display captured by NASA cameras. Scientists say that the event won't have a significant impact on Earth.

NASA says the flare peaked Tuesday and created a large cloud that appeared to cover almost half the surface of the sun. Images were recorded by the orbiting satellite called the Solar Dynamics Observatory.

A news release says solar energy released by the event should deliver a "glancing blow" to Earth's magnetic field on Wednesday or Thursday.

But it's not expected to cause a major impact here. The National Weather Service is predicting minor effects on satellites and weak impacts on some power grids.
