    I think actually the object is egressing from Earth's shadow at every pass,
    which makes sense given the northern hemisphere's summer shadow geometry.
    This happens at "max altitude" because it isn't visible until that point.
    
    Correct me if I missed something, Chris.

    This can't be correct...
    
    >MAST's orbit is well placed for evening observation at latitudes
    >north of about
    >40 N. Heavens-Above has elements.
    
    ...if you look at H-A's chart at...

    (for my winter viewing location in Lewisburg WV)
    
    The "Starts" column is identical to the "Max Altitude" column, 
    suggesting that the object comes out of eclipse at culmination for 
    each and every apparition, regardless of the time of day or position 
    of the sun.
    
    That just can't be, can it?  What gives Chris?
