    Re: Refraction. was: Bubble Horizon Altitude Corrections

    M.G.J. Minnaert wrote a book entitled "Light and Color in the Outdoors"
    (originally in Dutch in 1937, revised until 1974) which was translated into
    English in 1992 and published by Springer-Verlag.  There are chapters about
    light reflections, light refractions, the curvature of light rays in the
    atmosphere, the Purkinje effect, seeing underwater, illusions, fogbows,
    rainbows, halos, coronas, Parry's arc, Haidinger's brush, distribution of light
    over the sky, crepuscular rays, the zodiacal light, luminescence of the sea, and
    an appendix on measuring angles out of Doors.  It has many fine illustrations,
    some equations, and tackles many optical phenomena as scientifically as
    possible.
    
    Highly recommended reading appropriate for such questions!  To wit, there is an
    photo of a "superior mirage above cold water: a tanker below the horizon appears
    upside down in the mirage" above the horizon.  Fascinating...

    OK ladies & gentlemen.  We have the case of a mirage, where the image
    rises above the desert floor.  Are there any counter examples of an
    image sinking below the horizon?
