    Re: Etymology of "loom"?
    From: George Huxtable
    Date: 2009 Sep 12, 18:04 +0100

    None of those definitions of "loom" that have been offered seems to accord
    with my own understanding of the term, which occurs when you see the loom of
    a lighthouse. The light itself is below the horizon, but what you can see is
    the rotating beam swinging around and illuminationg low-cloud or haze in the
    air above it.
    
    Then, the loom is nothing to due with refraction, it's simply scattering of
    some light from the brilliant beam into the observer's direction.
    
    My experience, in UK waters, is that such a phenomenon is perfectly normal,
    and indeed to be expected. Seldom does the light itself come into view
    before it has been preceded by its loom. No doubt that's connected with our
    famously-damp atmosphere.
    
    George.
