Back Right CIVA Image

This is a tweaked version of the back right CIVA image. This was assumed to show the ground surface of Philae's alcove. In fact this shows that the area is full of cryorocks too. The brighter areas are a continuation of the bright cryorock seen at the front right of the alcove, the published two picture mosaic. The top half of this cryorock is dark indicating it has been in permanent shadow for some time. The brighter area indicates this part of the cryorock does receive some direct sunlight, although the cryorock front right of the image and closest to Philae is dark, indicating Philae is in shadow from the alcove wall on her left. There is a cleft in the left wall which probably allows sunlight to fall further back onto the brighter area. Despite my best efforts it is still quite difficult to make out the shapes of the cryorocks. I found it helpful to look at the image full screen through almost shut eyes. The next image is an annotated version which might help too. Credits: ESA/Rosetta/NAVCAM – CC BY-SA IGO 3.0
