I've been noticing that the images of Spirit's sundial have been appearing mottled lately.

The pattern looks the same in both left and right pancam images so I believe this is not dust on the lens nor a compression artifact. I think Spirit's driving, and particularlly dragging the stuck wheel, has produced enough vibration to cause the dust on the sundial to clump. This may be happening on the solar panels too. Has anyone noticed this in images of the solar panels or heard if the power levels have been climbing faster than expected?
