"The twin STEREO spacecraft (called Behind and Ahead denoting their relative positions in space), now almost 120 degrees apart, captured this large and dramatic prominence eruption over about a 30-hour period between Sept. 26-27, 2009. Prominences, called filaments when they are viewed against the surface of the Sun, are clouds of cooler gas suspended above the Suns surface by magnetic forces. This erupting prominence was large enough that both spacecraft were able to observe it for hours on end, one of the first times that has occurred."

"From the Behind perspective (on left) the long filament, darker than the Suns surface, can be seen rising up and then breaking away, spreading out above most of the Suns surface. As seen from the Ahead spacecraft (right), the filament is seen in profile and is therefore called a prominence. The very large cloud lifts up, breaks away, and heads out into space. This is one of the most spectacular eruptive prominences either SOHO or STEREO have observed." -- 10-06-09

"This is one of the most spectacular events that the STEREO mission has observed."

"Scientists are interested in observing the profile view (as seen by the "Ahead" spacecraft),
as it confirms the model that prominences move from high solar latitudes toward to the
Sun's equator. The prominence observed follows the path of the solar magnetic field,
which changes form during the 11-year solar cycle. The shape of this prominence is
characteristic of the solar minimum which is the quietest solar minimum in a century."
