    Re: Lat/Lon by "Noon Sun" & The Noon Fix PROVE IT
    From: James N Wilson
    Date: 2009 Apr 15, 11:39 -0700

    George:
    
    A difference between my method and Frank's is that I establish two slopes
    of the altitude time line, rather than look at the entire curve.
    Accordingly, I need a few more measurements early and late, since I can't
    establish accurate slopes from the data you presented. For this latitude,
    I would start 30 minutes before estimated LAN, and establish the second
    slope from measurements in the same altitude range as the first set. Can
    you give me this data? It's work for me to read Excel, so the data in
    tabular format would be fine.
    
    Additionally, I read the declination around noon UT on December 21, 2008
    as S23�26.4'. I translate that to -23.434 decimal. Did I miss something?
    Perhaps I should just use what you gave. It's not a problem.
    
    Thanks.
    
    Jim Wilson
