Scientific paper

We study the spatial distribution and temporal evolution of coronal loops using data from the Solar Dynamics Observatory (SDO) Atmospheric Imaging Assembly (AIA). We apply an automated coronal loop detection algorithm that is maximized for accuracy and completeness, and reconnects orphaned segments of coronal loops, to extreme ultraviolet images of the solar corona. We quantify the loop size distribution with a scaling index in each of the SDO AIA passbands, and show how this changes with time. This provides new insights into the physical mechanisms that create coronal structure.
