Evolution of solar activity is also visible on the solar limb in the form of plasma structures known as prominences
that hover, quiver, and occasionally erupt into space.

There's no comparison in grandeur between such pip-squeak arcs and the mighty solar prominences

are caused by the same magnetic forces that can lead to solar flares and CMEs, although how the phenomenon is formed remains unknown, according to (http://www.nasa.gov/mission_pages/sunearth/spaceweather/index.html#q1) NASA.
can last anywhere from minutes to months and can change appearance rapidly, depending on the stability of the magnetic fields holding them aloft.
, which often appear as thick ribbons of gas swirling high above the sun's surface, do more than make a pretty picture.
