    The video to show a magnified view of the sky, this is why the velocity 
    appears fast.  The person who recorded the video stated that he could 
    only see the object through the camera lens, not by eye.
    
    Using the moon as a reference I calculated a velocity of 7,775 m/sec (I 
    assumed that the object was in stable orbit).  This is a reasonable 
    velocity for a LEO's object but I am new to this activity so I defer to 
    others who are more experienced.
    
    Best regards,
