a) Alternative view of the area with several honeycomb features. The honeycomb features are indicated by dashed white circles and numbered as in Fig. 12a. This image was taken roughly two hours after Fig. 12 during the flyby on March 28, 2015, at a distance of ~26 km. The trails of possible sources for observed sunset jets are indicated as well. b) Enlarged, unannotated view of the area highlighted in the white rectangle in a). c) Image cropped from Fig. 7 (taken on Septemper 19, 2014), showing the same area as in b). For better comparison, c) is co-registered to b). The dust cover appeared smoother at the corresponding locations of the honeycomb features six months earlier.
