This NASA image obtained October 21, 2010 shows a fast-growing sunspot 1112, crackling with solar flares. So far, none of the blasts has hurled a substantial CME, or coronal mass ejection, toward Earth. In addition, a vast filament of magnetism is cutting across the sun's southern hemisphere. This f
