    Re: Lunar distances
    From: Nigel Gardner

    Further to my last note, I had forgotten that I have a copy of 'Cloudy
    Weather' Johnson's book 'Nautical Astronomy Made Easy' subtitled 'The
    solutions of the various problems being effected by a small table on one
    page. Designed to economise time and labour'
    He describes the lunars as follows:- ' The value of the Lunar Problem as an
    independent means of determining the Greenwich Time in case of an emergency
    being generally admitted, attention is invited to the very simple method
    contained in this book, in which it will be seen that nearly the whole of
    the computation is made by means of the same little Table, so that the
    distance may be cleared and the Greenwich Time found with the utmost ease
    and expedition'
    The trouble is that his methods rely on having a tabulated LD from the
    Nautical Almanac.
