The image on the right shows a coronal cavity observed by PROBA2/SWAP along with its associated filament as seen in SDO/AIA data. Coronal cavities are believed to be the low-density cross sections of magnetic flux ropes.
A synoptic map (or a latitude-time map) of the Sun shows the evolution of the Sun over a given period of time in a single image. The PROBA2 team have created a synoptic map of the Sun for whole Carrington Rotations.
