SOHO: Pick of the Week (2012 Apr 13)

Heading in Opposite Directions
Two massive prominence eruptions occurred one right after the other on opposite sides of the Sun, as seen by the STEREO Ahead spacecraft over a six-hour period (April 7, 2012). ÿThe prominences are first seen lifted off from the Sun in the Helium II emission line at 304 Angstroms by the EUVI telescope (orange), and then followed out to several solar radii by the COR1 coronagraph (green). Solar prominences are unstable clouds of gases suspended in the less dense, million-degree solar corona by magnetic forces.
