To me, the prominence looks to be the product of one of two possibilities.
First, it is the later stages of a "regular" arcing prominence that has become
detached from the field lines that that begat it and is in the process of
falling back to the surface. Take a look at the APOD that showed the animation
of that huge CME the other day. http://apod.nasa.gov/apod/ap110610.html
You'll see something similar toward the end. Second, it could be the material
you see beneath the large cloud it the rest of the prominence. In other words,
the prominence is "normal", but extending toward you rather than across your
field of view. In either scenario, I'm sure it is actually quite turbulent.
