Important notice about STEREO Behind
On May 30, 2011, the STEREO Behind spacecraft caught a prominence in the process
of leaping from one part of the Sun to another. In this movie, combining images
from the EUVI and COR1 telescopes, the prominence is first seen erupting by EUVI
in images taken in the Helium II emission line at 304 Angstroms. At higher
elevations, it is seen in white light by the COR1 telescope. In the COR1
images, the prominence pauses. Some of the prominence material drains back
down, but most of it is deflected to the north, and ends up raining down on a
completely different part of the Sun, far from where it started. This is very
unusual behavior for an erupting prominence, and this event is sure to be
carefully studied by scientists.
Some out-of-focus dust particles just in front of the COR1 telescope are briefly
visible toward the end of the movie.
