    Managed to image Discovery and the external tank from Dorset, UK under clear 
    skies.  Both objects became very bright within a few seconds reaching about 
    mag -4.  The tank followed virtually the same track as Discovery and so on a 
    30-sec exposure with a 10-mm f.l f/3.5 lens (Canon EF-S) their trails 
    merged.  They faded to about mag -2 as they reached the zenith, one passing 
    in front of the other giving a three-dimensional perspective to their 
    motion.  After crossing, they continued to fade disappearing in the 
    constellation of Orion.
    Well worth setting the alarm for - as well as being able to take a few 
    hundred images of epsilon Aurigae before dawn.
