   Ahh, there is a small white feature well to the left of the "bug" that can   
   serve   
   as a landmark.   
      
   The distance on my screen from the small white feature to the "bug"   
   is 8 inches for the image on the left (Sol 2 pancam), which puts it just off   
   the   
   right hand edge of the screen for the right-hand image (Sol 5 navcam).   
      
   So the navcam image is just outside the range that would reveal the "bug."
