*MAJOR SOLAR FLARE:* Today, Earth-orbiting satellites detected the 
biggest solar flare in more than 3 years. The M4.4-category eruption 
produced a shortwave radio blackout over some parts of Earth and a 
bright coronal mass ejection (CME). Remarkably, the flare was even 
bigger than it seemed. The blast site is located just behind the sun's 
southeastern limb, so the explosion was partially eclipsed by the body 
of the sun. Visit Spaceweather.com
