http://www.space.com/16400-solar-fla...fireworks.htmlThe sun erupted with a powerful solar flare Monday (July 2) in an early solar fireworks display just in time for the Fourth of July. A wave of plasma from the flare could reach Earth by the U.S. Independence Day holiday on Wednesday, July 4.
The sun storm came from a large sunspot called AR1515 that is now rotating across the Earth-facing side of the sun. It unleashed an intense solar flare at 6:43 a.m. EDT (1043 GMT) today in what is expected to be one of several strong solar storms in the days ahead, space weather officials said.
