   It looks like you are correct.  There is a small white feature to   
   the left of the same "row" that indicates these are equivalent   
   regions.  The "bug" is gone in the navcam image.   
      
   Either it blew away, or walked away, or ...   
   Does anyone know if the "bug" has been seen in _any_ image   
   other than the Sol 002 panorama?
