You can see the prominence form, rise up, and then erupt away into space over the course of one day, on October 6-7, 2012. Sometimes this material rains back down to the surface, and sometimes it escapes entirely.
A prominence is a large bright feature extending outward from the Sun's surface, often in a loop configuration. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona.

Prominence A cloud of cooler plasma extending high above the Sun"s visible surface, rising above the photosphere into the corona.
A region of cool (104 K), high-density gas embedded in the hot (106 K), low-density Solar corona. Prominences are the flamelike tongues of gas that appear above the limb of the Sun.

The apparent drift of a star across the sky, compounded from the motion of the star and the sun.
prominence - (n.)
Solar gas protruding over the limb, visible to the naked eye only at eclipses but also observed outside of eclipses by its emission line spectrum. Prominences are at approximately the same temperature as the chromosphere.

Caution: looking directly at the Sun can damage the retina and one's eyesight.
Finally, solar prominences rise up through the chromosphere from the photosphere, sometimes reaching altitudes of 150,000 kilometers. These gigantic plumes of gas are the most spectacular of solar phenomena, aside from the less frequent solar flares.
