Description: Fast-growing NOAA active region No. 11112, crackling with solar flares, surrounds a sunspot group in the SW quadrant (lower right). On October 16, 2010, this region launched a CME, or coronal mass ejection, toward Earth. In addition, a vast dark solar prominence cuts across the sun's southern hemisphere and links with the sunspot group. This prominence (filament) is so large it spans a distance several times the separation of Earth and the moon.
