    Re: Mirages, was: Refraction

    I am not sure what happens at sea but I know though bitter experience that
    things do sink below the horizon in desert environments. Many times in early
    mornings I have set a course towards a distant mountain, which appears as a
    bump on the horizon then as the day wears on it slowly disappears.
    
    This is remarked on numerous times in the journals of Australian explores
    that they could see things that were actually over the horizon. I read an
    explanation of this phenomenon once but the answer now eludes me. I think it
    is something to do with refraction and occurs in my experience most often at
    dawn and dusk.

    Frank,
    
    The star question has been covered to my satisfaction (at least to my
    inexpert standards!).  But I also posed the earth-bound question along
    with the star question.
    
    I am specifically wondering whether a ship could ever appear to sink
    below the horizon even though it actually was above it.  My
    understanding is that normally ships appear higher than they really
    are.
    
    Thanks,
    
    Fred
