The latest storm , which began Monday, was one of the best documented solar storms to date. Almost simultaneously, NASA's WIND spacecraft began detecting bursts of radio waves from electrons involved in this magnetic storm. Supersonic waves rippled though the solar corona as a puff of high energy gas shot out into the Solar System . The above image shows two photographs of the Sun taken about 15 minutes apart and subtracted, highlighting the explosion. The CME gas will have little lasting effect on the Earth , but might make this a good weekend to see an aurora .
