Double Prominence Eruptions

Within a one-day period, two substantial prominences broke away from the Sun (Sept. 13-14, 2013). The images were taken by the STEREO Ahead spacecraft in extreme UV light. Prominences are unstable, cooler clouds of gas suspended above the Sun by magnetic forces and are often observed collapsing or breaking away from the Sun.
