We're starting to see some clouds as we head towards winter. Here's an navcam animation from 4793:

This is a stretched difference of each frame from the average of the frames.

Hi Fred,
The originals have that bright 'half moon' in the lower third of the frames (which I think you chopped off)
What is that bright area?

It is caused by the dust of times. ;-) The small hood we have in front optical element only partly occludes the Sun. Therefore, even when the Sun is outside the field of view it will illuminate the dust which causes diffusion and enters the optical path. Most of the dust was accumulated around Sol 1200+ (2007) but during the years the wide have cleaned up the front elements quite a bit.
