    Lunar Distance in Wikipedia
    From: George Huxtable
    Date: 2007 Jul 22, 22:18 +0100

    I've just been delving into "Lunar Distance (Navigation)" in Wikipedia, and
    can quote this little gem-
    "[edit] Theory
    If there are two people, one at Greenwich and one 15 degrees West, the time
    by the sun will be one hour later at 15 degrees West. So, if the person
    observes the position of the moon at Greenwich at noon and another person
    observes the moon 15 degrees west of Greenwich at their locally determined
    noon, then due to the one hour difference, although the sun is at its
    zenith, the moon would have moved approximately its own diameter across the
    sky."
    
    =========================
    
    Just checking that I'm not making a silly error here. At the same moment,
    when the time by the Sun is noon for the observer at Greenwich, then for the
    observer at 15 degrees West, won't the Sun still be climbing up the sky? And
    so, won't his time by the Sun at that moment be 11 am, one hour earlier,
    rather than one hour later?
    
    Looking at it another way, however, when it's noon for the observer at
    Greenwich, it won't be noon for the observer at 15 degrees West until an
    hour later.
    
    I thought I understood the matter, but now I am thoroughly confused. What is
    the fellow trying to tell us? I wonder who wrote it?
    
    George.
