    Thanks!

    At the moment of Sun setting, I was busy with Venus observation
    (I spotted it few minutes before the sunset), while Bill was taking
    a walk towards the end of the jetty protruding to the lake
    (and was chilled so much that he turned the heater in the car
    when we were going back 1/2 hour later, while I was suffering from heat).
    
    We also had an artificial horizon, but who uses an artificial horizon
    when the real one is available:-)
    
    If this explanation is correct and accounts for all our systematic error,
    then the shape of the Sun was like a sort of mango or a lemon which had
    to be visible by the naked eye. Unfortunately we were not looking at the
    Sun when it set.
    
    Alex.
