    Re: V-Correction for Sun?

    Sean,

    So I was right when I said, "I know of no other program that even attempts to reproduce the Nautical Almanac values for the hourly GHA of the Sun."  Now I know of one.  Based on that value, I would have to say that Astro-Nav does try to reproduce the Nautical Almanac values, and possibly, even probably, better than Celestial Tools.

    According to my records, I downloaded the free version of Astro-Nav in August of 2011.  The free version only works for the year 2008, and the 2008 Nautical Almanac is missing from my collection, so I did not continue investigation.  Mea culpa.  However, I did contact them regarding discrepancies in their Increments & Corrections tables (as apparently you also found), and, though they did respond, I was not completely satisfied with their answer.

    Thanks for making me aware of this.

    Stan

    Stan,
    AstroNav's "almanac" function for 12h UT on 1 Jan., 2016 shows 359°10.2'. I'm not sure if this is the same value that AstroNav uses internally for other calculations.
    Regards,
    Sean C.
