AIA 171 Å image and a sketch of several features we wish to draw attention to. In light of Figure 21, these features might be composed of bundles of thin strands, or they might be ribbons of non-uniform thickness. Note in particular how the loops become dimmer as they get wider, even at the same height above the surface. This observation may be evidence of their oblate cross-sectional shape. Also note the flat loop tops, which are also consistent with the hypothesis of their oblate cross section.
