US-SUN-GIANT SUNSPOTS
This 29 October, 2003 NASA Solar and Heliospheric Observatory image shows several giant sunspots crossing the face of the Sun. One of the most powerful solar flares in years erupted from giant sunspot 486 early 29 October. As a result of the explosion, a severe S4-class solar radiation storm is underway. The explosion also hurled a coronal mass ejection (CME) toward Earth. When it left the sun, the cloud was traveling 2125 km/s (almost 5 million mph). This CME could trigger bright auroras when it sweeps past our planet perhaps as early as tonight. AFP PHOTO/NASA
