    Re: Lunar Distance in Wikipedia
    From: George Huxtable
    Date: 2007 Sep 9, 18:49 +0100

    We discussed the several discordant published dates for the end of lunar
    distances in the Nautical Almanac (the British version)
    I now have an authoritative answer from "the horse's mouth", to wit,
    Catherine Hohenkerk of tHM Nautical Almanac Office.
    She writes-
    "The "NA" for 1906 was the last year to contain lunar distance tables,
    but instructions on how to compute and reduce them were included until
    Note that before 1914 the "NA" (for astro-navigation) was entitled "The
    Nautical Almanac & Astronomical Ephemeris, Part 1", and 1914 - 1951 it
    was entitle "The Nautical Almanac Abridged for the Use of Seamen"."
    That is in accord with the date that was given by D. Sadler, and qoted by (I
    think) Frank Reed. Sadler was Superintendent of the NAO, so as Catherine
    says, he ought to know.
    So now that's a definite date, which can go into Wikipedia, if anyone (such
    as Renee) is willing to do that at some future reiteration.
