    Interesting!
    
    For those who can't see the movie (and who care!), it's a very 
    small dark object moving in a straight track silhouetted by 
    the sunlit Moon.  In places along the track there are 
    after-images or something almost like "mouse tracks" on an old 
    notebook computer (air turbulence?)  In size it's almost like 
    illustrations I've seen comparing the sizes of the Earth and 
    Sun.  It appears to cross at least half of Moon in about six 
    seconds, but it's hard to know for sure as only a portion of 
    the Moon is in the frame.  The object's shape seems to change 
    in an irregular manner.  I'm not good at geometry and so don't 
    know if the geometry would permit this, but to me it looks like 
    it could be a bird or bat (or even an insect?).  I'd like to 
    know which direction it was traveling.  In the upper right 
    there's a small but very bright crater close to the Moon's limb, 
    and on its path from lower left to upper right it traverses that 
    crater.  Of course the time and observer's location would be 
    helpful!
