Scientific paper

An analysis of C IV movies of the solar limb have revealed two distinctly different classes of loop structures. Those of the first class appear to be ejecta, show proper motions of the order of 100 - 200 km/sec, follow trajectories along magnetic field lines, and have an uneven intensity distribution along their lengths. The second class is quasi- stationary, and the intensity obeys an apparent scale-height law (i.e. an exponential decrease of intensity with height above thesurface). Analysis of the scale heights under a straightforward set of assumptions allows us to determine a temperature parameter that is substantially higher than the ionization temperature. Structures of the second class do not show proper motions in the movies, but appear to form in place, suggesting that they result from the cooling of hotter plasmas.
